Hey Rick - Welcome to the gang! As you can see, not a problem as long as you plan accordingly, and are flexible.
And if you are planning to be on the road for long spells, do get an RV that you both can 'live in'.
As you do your research, consider both the towing capacity as well as the coaches total CCC. I assume your van, or planned van, will have brakes - good. I'd look for bigger engine coaches. Cummins ISM or ISX, I personally like the ISM for 40-42' lengths. BIG CAT C12-15. Or Detroit engines. I'd want to be sure these Big Blocks have the three stage Jake brake, or if Foretravel, the retarder transmission. I personally like the extra stability while driving, let alone towing what you plan to, of Tag's.
Not that a Cummins ISL or CAT C7 or C9 could not pull your van, sure it could, with just a bit slower hill climbs. But, those BIG BLOCKS provide much more Compression Braking HP for you on the downgrades, and that is a nice safety feature.
Good luck on your hunt and setting up of the Rolling Man Cave,
Smitty
