Just bought a Wolf Creek 840 -- Set Up Questions

I would definitely do the Fastguns, 8.5’ camper on a 6’ bed, yes you will need a Superhitch so you can run a Supertruss. Is you Wolf Creek going to have a Fox landing? If yes you will need a longer hitch extension than 18”. Will your new Ford have a rear swaybar? If no then you should consider one. I like Timbrens instead of air bags. I would do the Timbrens first then a swaybar if there is still too much sway.
For your AC, install a MicroAir on the AC and then use a Honda 2000i/2200i generator.
