You can get a roll on champion generator for a few 100 $$. You'll only need it to run the air or charge the batteries. Just roll it out when you roll out the bike. Keep a gas can in the truck bed.
you might appreciate a front bedroom when on the road and you want to overnight it without unloading.
The Ford has a good reputation. it should pull a light weight 25 footer.
I have a lightweight 5th wheel, not sure if they make them anymore. But it's easy to hitch and pull. Has a front bedroom.
