looking for TT manufacture recomendation for dry camping

We dry camped in a Keystone Bullet many times at National parks and found it was up to the task, However we upgraded to an Airstream and we found that these TT were much better prepared for dry camping, Our unit came with larger propane tanks and 2 batteries. Add a generator and we were ready to go. they have a good selection of units in the size you are considering, I also think you will be impressed with the towing experience when out traveling with an Airstream.
