Tanks on the old 81 Sunline 16' TTs

I Googled in vain to find out how many gallons of water our little 1981 Sunline 15.5SB carries and how large the waste tank is. No booklets or pamphlets came with it. Where can this information be found? Norman? Don't you have the same TT? :wink:
 
Water Capacity

We basically have the same fluid capacity.

We manage five days when we have a place to shower. The limit is the amount of water available and the capacity of the grey tank.

We can go a little longer if we dump the dish water down the toilet or outside.

The Black tank can last us a week.

18 - Fresh Water plus 6 in Hot Water
10 - Black
21 - Grey

When we're connected to water as we are now I dump every four-five days. We typically don't camp even with full hookups with either the grey or black valves open.

Oh the toilet has a 10g tank? We wont be showering in the RV. We'll use the CG showers. I just wanted an idea on the size of the tanks. We're also taking more disposable stuff with us this year so less dish and utensil washing. I also bought 2 dishpans so any graywater can be dumped outside.

Do you travel with your clean water tank full or fill up when you get to your destinations?
 
Showers

We typically use the campground showers as well.

When we travel we always carry at least a half tank of water. If we are going to a place without water we travel with a full tank.

Even when you're camped in a full service campground the water system sometimes fails, we've had it happen twice this year with two campground waterline breaks.

As well often when winter camping it's necessary to disconnect you're input water line due to night time freezing conditions.

Another benefit of disconnecting your external water line in freezing weather is that it depressurizes your internal waterlines, leaving a small additional margin for freezing of internal water lines.

We once froze the waterlines input waterlines inside our Bounder with out any breaks. I suspect we were ok because the lines weren't pressurized.

Many campgrounds frown on that plus it is illegal in some states including NY.

We always travel with our fresh water tank at least 1/3 full. Never know when you might need to wash your hands, flush the toilet, water the dog, etc.

We do both depending on the camp or time of day. Going to a park with known unpleasing water, we bring our own. On parks with known good tasting water we fill up at the park. When we fill up at the part, we "always" use a filter. The amount of sediment and rust in CG's can be shocking :shock:

When we travel in to camp on a Friday night late, we sometime haul form home to save time with camp setup. Now that we have the new camper and truck the additional water weight is not a problem.

At our State Parks they have a special gray water drain post every so many campsites. Sometimes they are hooked to a collection tank, other times to a crushed stone bed. Point is they provide CG wide gray water collection spots that is normally aimed at the tenters but all can use for dish water etc.

Good advice and it makes sense. I don't think we'll be doing any cold weather camping though. :D We plan to start in late April after the last freeze here in middle TN.

Doesn't the heat from the camper keep the lines from freezing? They seem to be under the bed and sink. I haven't looked underneath to see if any are exposed.

We wouldn't dump gray-water where it isn't allowed. Having the fresh water tank part full does sound like a good idea.

I don't understand what kind of toilet we have. It doesn't seem to be connected to the water supply. It sits on a tank (waste tank?) and has a black-water outlet to dump that tank. I wish we had gotten the book with it as we did when we bought the Dodge Xplorer. It's different than the one we had in the Xplorer.

Norm... does this toilet need water or chemicals added?
 
Water and Toilet

The water lines in your trailer are very safe as long as you have heat on. The lines that froze in my rig were in my motor home.

Generally when we travel we don't have our heat on at night, we use an electric blanket at night. However, though the rig gets cold, we have not had the internal temperature drop below freezing though the outside temperature has been well below freezing. The Sunline's pipes are relatively safe.

The outside hose is another matter. We always disconnect if there's any chance of overnight freezing. We have had a hose destroyed by freezing.

You are correct about the toilet; it does sit on top of the black tank. It is connected to the water line at the rear of the toilet. Water to the toilet is controlled by the first little lever on the right rear corner of the trailer. The bigger lever flushes it.

It's possible to download the manual for your toilet, actually this is true for practically every appliance in the trailer. I'll look later and see if I have the toilet manual.

We do carry chemicals with us for the toilet. We use TST RV toilet treatment and buy it at Walmarts. We use it probably every other dump period.

The use of chemical treatments is a sticky subject. People use all kinds of 'stuff' and I don't have a real basis for what I do.

It's highly unlikely we'd get caught in freezing temperatures since we'll be doing warm-weather camping. I would camp in winter but my better half doesn't find the idea appealing. We'll be carrying a cheap lightweight electric heater for those chilly summer nights up north. No use using the furnace since the CGs include electricity.

Since we have chemicals left over from the Xplorer, we'll use them up and if there's no odor problems without them when they're gone, I'd rather pass. :)
