Help with pickup for 5th wheel

In my opinion you should get a one ton diesel dually, takes all the issues out of towing with a SRW because its ready right out of the box to pull and handle most pin weights out there. Eight foot bed, B&W 5th wheel hitch rated to next weight rating over your gross weight of the camper your looking at, 16000 lb RV get a 18000 lb rated hitch. Generator, well that's another issue. Onboard Onan gen has a lot of pluses, but also some minuses on a standard 5h wheel. On 5th wheel they are usually propane powered unless you can get dealer to add a gas tank in the rear underbelly of your RV which most 5th wheel toy haulers come with, propane gens will use most of your onboard propane but they are said to run cleaner than gas. If you only have one AC on your RV then you could get by with 2 Honda 2000I or equivalent brands and carry them and hook them together to run your RV. If your planning on staying in RV parks most of the time then you might be ok with the onboard propane gen, otherwise look at the gas option and/or the portable gen option. Another option would possibly be to look at the 40-42 ft toy hauler floorplans as they have bigger waste and fresh water tanks, most already have onboard gas tanks with gens wired and ready to go, have a little less living space if you use the garage as a garage but most have carpet packages to use the garage as additional living space.
