jaycocreek, I have 60 gallons of water capacity in my Host. We can easily make a week, but we could also easily go get more water and dump again if needed. Most of us here don’t have thousands of dollars of Torklift products to stabilize our rigs. You must have never priced their products.
Gjac, the general thought is that towing and stability is more stable with a fifth wheel. However, that has more to do with pin weight, and I’m not sure how much pin weight you are going to be able to have realistically on a F150. Fifth wheels are also quite a lot higher which means more wind resistance and more rig to catch wind with 1-2 ft more height. For the F150, I’d probably just stay with a TT and perhaps go with a double slide model to gain a little more space inside and use the bed of the truck for overflow storage of lighter items.
