I'm just speaking from experience because our 2653 had the tire in the center and the bouncing of it (on wonderful MI roads) caused our welds to break. It never broke all the way, but we found it was very close to falling off when we got home. We never had anything besides the tire mounted on the bumper, ever.
There's an option here, guys. Right now, I have my rear bumper off so that I can install skid wheels on the TT. Looking at the bumper, at least in '99, Sunline intentionally under welded the bracket to the bumper. The bracket is a square piece of metal that connects to the bumper stock, and instead of welding it on all 4 sides, it is only welded on two. It would be very easy to get the other two sides welded, and even to add an extra support bracket under the bumper that connects to the frame. You could easily increase the weight carrying capability of the factory bumper by several hundred pounds.

Remember that Sunline rated the bumpers at 100# so that we owners would not hang too much stuff on the bumper. It was an attempt to make sure that we didn't shift too much weight to the rear of the trailer thus removing weight from the tongue.

One dealer even told me that Sunline had told him that it was intentional that the bumper would break if overloaded.

Now, like JohnB with his negotiation with Sunline to add an extended bumper and cargo box on the rear of his 2499, you would have to be fully conscious of any extra weight you put back there, but if you just wanted to strengthen the bumper a bit for your spare tire, I would have to believe that adding some welds to the bumper mounting and maybe even adding a support bracket under the bumper would not compromise the loading balance of your unit. And it would give you great piece of mind about the ability of the bumper to safely and securely carry that spare tire.

Jon,
When you mentioned the roads in Michigan, I realized where you were coming from, literally. I have been to Detroit and the roads around there are simply atrocius! I've never encountered roads that were more rough. Those roads could break welds a lot bigger than those on the bumper! No matter where I end up mounting the spare bracket, I'm going to pay attention to the bumper welds!

Steve,
Nice suggestion on beefing up the bumper welds! When the fellow delivered my trailer to my house, he backed it in the driveway. The skids got pretty twisted up. They are way past straightening without cutting them off first straightening and re-welding them. I have been thinking of skid wheels, instead. Are you using the Paktron wheels? What size wheel?

Thanks,
Rick

Rick:

I had the 5" poly wheels installed on my 2553. They have worked well so far. My dealer told me the steel replacement wheels are interchangeable in the event that the poly would not hold up.

I bought 1000# rated swivel casters from Northern Tool. They are 5" by 2"wide and have zerk fittings on the wheel axle and on the swivel. The wheel is solid metal.

I am getting some 1/4" steel plate stock to make up the mounting plates and then will fabricate and install them, hopefully by the end of the week.

On the bumper issue, I would be very comfortable installing support brackets that connect between the bumper and the frame, and beefing up those welds as I mentioned previously.

I would not suggest doing this to increase the carrying capacity of the bumper but rather to simply insure that the bumper would safely and securely carry the spare tire. It's more a peace of mind thing, really.

Steve, that is really true. They didn't want anyone mounting hitches on there for pulling second trailers and stuff. When our bumper broke, my dad reinforced it with large L brackets bolted directly to the frame and bumper. He did no welding on it. That thing wasn't going anywhere.

Rick,

You can say that again!!! The worst part is when you're coming in on 75 from Ohio, I guess just from the state difference. Ohio used to keep 75 really nice just over the border, but it's not like that as much anymore.
