Sunline Camper Actual Loaded Tongue/Pin Weights

Hi Fellow Sunliners

To help someone thinking about a certain Sunline model and how it will work with their Tow Vehicle, I put this tongue weight chart together for comparisons.

These are actual “Loaded” camper tongue weights as measured on a Sherline tongue scale. I picked up most of these from the Sunline Meet and Greets. Everyone has different amounts of “stuff” however these are real camping weights. Your particular floor plan and where you can load cargo and how much of, will drive the loaded tongue weight both up and down in amount.

The back of your truck, (the receiver, the WD hitch and the rear axle/suspension/tires,) has to accommodate these weights. Often times on the lighter tow vehicles and even heavier ones, tongue weights can be over looked or not realized until later down the road. Hopefully this chart will help folks in the future get a closer understanding of where their camper loaded tongue weight may end up.

As I collect more Sunline tongue weights I will update the chart. If someone knows their loaded tongue weight and I myself did not get it, we welcome you to post it here along with year and model to add to the list. There are also about 2 of you out there where I did not record the actual weight, I’ll PM you and see if you remember.

Hope this helps

John





Edited 1-1-2010 to add additional tongue weights

John,

When you weighed the tongue on our '99 T-2453, it was somewhere around 820, if I remember correctly.

The trailer is 5,500 GVWR, catalog says 4150 dry, sticker say 4199 dry, and dry tongue weight of 538.

More Data

Year 1982
Model 15.5SB
Trailer GVWR 2630
Catalog Dry Axle Weight 1615
Catalog DryTonge Weight 150
Catalog Dry% Axle Weight 9.29
Camper Load Tongue Weight 160
Camper Loaded Weight 2309

These are the figures for my trailer. Note the dry percentage tongue weight for this trailer is very low per factory specs. As well we have no air conditioner.

The tongue weight is lower since I added two solar panels adding 40 pounds to the roof of the rear of the trailer. This reduced my tongue % tongue weight to 7%.

Before this modification my loaded tongue weight was around 200 lbs.

Thanks Norm, I'll update my sheet with your info. Yours is unique to the older models even in the dry state. Your note also jogs my memory to finish the 10% tongue weight post... Maybe this weekend as it is 17 F out right now...brrr

To John B, read your excellant thread on tongue weights and your diagram of the 2499. We are looking at several used mods. namely 2362 and 2499 in the 2006, 2007 yr. range. Dry weights at 4200 and 4785. If we add 1000lbs of stuff at 10% hitch weight that would be 520 and 578 on the hitch.
We plan on towing with our 2005 Nissan Frontier crew cab with trailer towing package. This is rated at 6000 lbs tow capacity with a 600 lb hitch weight. I realize we're close to max here but with an equalizer hitch couldn't some of that weight be transfered to the trailer? Only two of us traveling no pets or kids, RETIRED! We realize it is important where you load stuff and I do have some experience doing this as I owned a 21' Sunline back in the late 70's. We are planning a trip cross country, National Parks, and I keep shying away from the 2499 because of weight. Of course my lovely wife likes the floorplan of the 2499 better.
Thoughts or recs? Don Keneagy

My weights were a little higher when we returned last January. I took the unit directly to the scale on the way home hoping to capture a typical weight. The scale weight on my 2363 was 5550. The tongue weight was 800. I have two 6 volts and twin 30s.

The Durango was way over with the tongue weight at that level. While I had replaced the OEM tires with Grabber LTs I still could not justify the GVWR of the Durango. We made the decision that to safely maintain our lifestyle, kayaking, backpacking, fishing, etc. on a four month journey we needed to make a change. We replaced the TV with a 2500 truck moved gear from the unit to the bed and now can absorb the tongue weight and keep the unit at a lower gross.

Don,
Welcome to the club. We have lots of very knowledgeable people here willing to answer all your questions...

I know John & others will give you thier expert opion.
My non expert opion is forget the 2499.
I did the cross country trip to most of the parks out west, you will have a lot of mountains to climb and I think the 2362 is even a bit much for your TV...........JMHO

What is the size of the engine in your TV ? ..I am guessing it is a V6 4L 265hp ?

I know I don't have the average setup, I like a lot of leeway.

to luvrque, Thx for your quick reply,We just put an offer in on a 2006, 1950 which is immaculate. GVWR of 5500, UVW 3940 so I think I'll be ok with hitch weight. My 2005 Nissan has a 4.0 V6 with the factory trailer package. Final gear 3.357.
This trailer had been towed without an equalizer hitch but I won't.
I am amazed at all the knowledge on this sight and makes us like Sunlines even more. We are looking forward to our trip out West next year.
Dee and Don

Hi Don

Well I see you helped yourself by the time I was able to post back. And you came to a much better conclusion. The T2499 is a very nice camper, I use to have one, but it needs the right sized TV to line up with it. When I sold mine the tongue weight was 800# sitting in my yard, full propane, battery and the parts of a Reese DC hitch on the A frame. That is before 1 stitch of camping gear was added. That floor plan loads to the tongue as that beautiful rocking chair staring out the back window does not offer much counter balance. This kind of weights will be an issue on your truck.

The T1950 is a lot better at least in the tongue weights area. However you listed a 4.0 V6 with a 3.357 rear axle ratio. She will be working. Take it easy for sure. And see if you have an auxiliary transmission cooler. They can be added if not there. Another good idea is to look into a temp gage kit to be add to the transmission “pan temperature” to keep an eye on it.

The wind drag of a TT eats up towing capacity which is really different then hauling a sail boat or even cargo trailer. You will feel the front area of the TT once you start going over 40 MPH. Sunline helped by keeping the camper low to the ground and tapering the top front of the camper.

Good luck with your new camper. You have a good one there for sure. And welcome to the Sunline Owners Club. Ask away any anything, we always try to help. And we want to hear about the good times camping adventures too.

John

Dear John...........hmmmm, that sounds familiar.
I am quite sure (and much to my disappointment) you omitted my 2000' Advancer Ultra lite T25R from your tongue weight model. This Black Sheep stigma is a heavy burden.
But seriously, how would one go about getting an accurate tongue weight? I imagine I can sell it to the Scale Commodore down at the City dump to let me weigh my beloved Advancer on the dumps scales. Is it sufficient to put the trailer on the scale with the truck "off" for an accurate trailer weight?
I need to unhook from the truck?
Can I park the trailer off the scale and drop the foot on the scale (disconnected from the truck) to measure the tongue weight?

Hi Sky,

I did not omit the Advancer T25R, the opportunity did not come up... The list above was created when I travel to M & G's and offer folks a tongue weight reading if they would like one. Many take me up on the offer and from the TT's measured they get on the list. Or some one weighs theirs, tells me and we add it.

Having the list of actual loaded campers really helps when you are trying to buy the right WD hitch and know if your TV can hold up the TT. While everyone has different "stuff" using a loaded tongue weight from someone who camps beats any dry catalog weight for being closer to your possible loaded tongue weight.

Now how can you get a tongue weight? Well if you stop over you can one get for free here....LOL OK maybe a little bit too long of a trip...

There are a few ways. Since you are going to the scale with the truck you can get the truck weights too and see if your WD hitch is setup correct and how your axle weights line up to your TV and TT. We call this a towing weight check up.

You need these 3 sets of weights all by axle. Load the truck and camper as you go camping. If you have a 3 segment truck scale this gets easier but can be done on a 1 segment scale too.

Need front TV axle, rear TV axle and both TT axles weights for each of these setups. The 3 segment scale does them all at once. The 1 segment scale you have to pull forward to get an axle weight set one at a time.

1. TV and TT hitched on scale with WD hitch engaged. Take a weight set.

2. TV and TT hitched on scale with "no" WD bars engaged. Take a weight set. You can stand still from set 1 and just unhook the WD bar chains.

3. Drive off, unhook TT. Drive TV on scale and get front and rear axle. Take a weight set.

From those 3 wet sets and a little math you can determine:

  • Front TV axle weight in relation to front GAWR and if the WD hitch is set right.
  • Rear TV axle weight in relation to rear GAWR.
  • TV GVW in relation to the GVWR of the truck.
  • TV GCW in relation to the GCWR of the truck.
  • TT GVW in relation to the GVWR of the TT.
  • TT axle weights in relation to the TT GAWR.
  • TT tongue weight.
  • Determine TW percent to TT GVW for proper TT balance.
I can help with the math once you get the numbers if you need what to do with what number.

If you only want tongue weight. Need 2 weights.

1. Pull the TT axles on the scale, unhook the WD bars, have the truck off the scale, have the truck still hold the tongue. Take a weight. This gets both TT axles weights only with no WD engaged.

2. Then back up and have the entire camper on the scale, unhook the TT, tongue jack on the same scale as the TT axles, drive truck off the scale. Take a weight of the entire camper.

Then subtract the entire weight of the camper, (weight 2) from just the axle weights. (weight 1). The differnece is the tongue weight at the tow ball.

If you just put the tongue jack on the scale is it off by the distance from the jack foot to the tow ball. If that is the only reading you get,(jack weight) at the jack foot, then give me the distance from the tow ball to the front TT axle center and the distance from the tow ball center to the jack foot center and I will calculate the true tongue weight at the tow ball.

Hope this helps

John
