It is really hard to find a nice boondocking TT. I have a 34' Avion and it is just way to large to get back where we want to camp. My wife gave me a choice, fix our old Avion C-11 camper or buy her an Airstream Bambi. I looked at the Airstream and it is nice, but it won't do the kind of boondocking that I wanted to do, especially since it held only 23 gallons of fresh water and less than 500# after it was wet. Since I couldn't find anything to fit my needs, I decided to put the C-11 on a trailer.
My specs, or wish list were:
Under 20' in length,
80 gallons of fresh water minimum,
100# of propane,
20 gallons of gasoline,
2 batteries minimum, I now can take 7 batteries,
Minimum of 1000# capacity after wet, mine will carry 1500#,
Capacity to take an extra quad,
After doing some extensive camping, the only thing that I need to do, besides mounting the TorkLift Power Max box (capacity of 5 more batteries), is to set it up for an outside shower. All this will require is a Camp Chef hot water heater hooked up to another LP tee, and an outside shower tent. I already have an external water pump with hose bibs.
Except for the extra quad, I would think that someone makes something close in specs. Boondocking RVs seem to be somewhat rare here in the US.
