[Roadside]

OK.... Well some of the problems you know from being on road already. So for a TC (Truck Conversion) or a HDT, pulling a fifth wheel trailer, you have some options. I think it is "Spacecraft" in Mo. will build anything you want, comes with a price. If you are doing it you self, for the most part. There are ways to build a very well built toy hauler type trailer. You not going to get the best fuel mileage with the type of weight you are thinking about hauling. 300 gals. of water.... that is a lot of water/ weight. Dose all this water need to drinkable ? Keeping a tank clean and setting still for a month or longer, might be alga problem, in hot temp weather. And when you get done using the water... where is it going to go...in a holding tank, or on the ground.?? Is trailer ground clearance a issue, so 10 to 12 in.? And is a HDT.. how big if a sleeper are you thinking about. Like day cab, small stand up sleeper, or condo full size ? Because you could get you a tractor and do very little modifications to the truck and build up the commercial trailer like you need. Trailer could be 38 to 48 long. Another place to get some ideas is a traveling show, large carnival, and race car haulers. Yes I know, a lot of them use commercial buss, they rent. But it can give you some ideas. They live in them for a show season, for the most part. The weight you are think about will put into a commercial trailer / truck bracket. AS long as you not for hire or working / selling in different locations, and have this for you own use, you will be ok. There gets to be a real fine line.... personal use and retail sales. Very different.
