1) Look at the Lance 825. Can find them used and it works with the short bed truck.
2) Instead of trying to carry enough propane in bottles, look at an under belly tank in the 50 - 60# range. Also, if you need to run the gen set 24/7, it would be cheaper to stay in a campground with electric hookup. In the winter time, a solar panel and fan will work.
3) Depends on the unit. Usually you can store it same type places you can a travel trailer or motorhome. Just make sure you let them know exactly what you are trying to store AND have some sort of support under it when it's off the truck for safety reason against wind gust.
4) I can parallel park my rig anyplace you can park a truck (not counting height).
5) Deisel definitely not required and unless you are driving LOTS, it's about an equal trade off between upfront purchase price and maintenance or weekly gas expense.
6) Advantage to the Hondas is you can only run one when needed for lights/recharge. Downside is they are easier to steal, especially if you want to try and have them running while you aren't at the camper.
7) About the same as getting out of the cab and getting in the truck bed. If I'm afraid of getting out of the truck, I wouldn't be able to sleep anyhow. Now the attacking and trying to leave - that is another issue - then again, where I feel comfortable taking a nap won't be an issue.
8) If I'm in a hurry, I can load or unload in under 15 minutes. However, typically its 25 minutes because I'm never in a hurry. Electric jacks would help speed it up, but the cordless helps. As far as camp goes, my quickest setup was 0 seconds, not counting turning the engine off. My FW hookup was under 2 minutes, but it took longer to setup with the rear jacks and slide-outs etc, making the total time about the same.
The propane and generator run time will be an issue regardless of a Class B, TC, TT, or FW. Basically, if you have that much heat you need to run the A/C continuously, save some money and stay at a campground if possible.
