Better topic for the Dinghy Towing forum, but for openers:
Somebody here will send you a link to Motorhome Magazine's archive of towable vehicle pages. In general,
More Manual Shift vehicles are towable than their Automatic brethren. In some cases it's sharper than the Continental Divide. For example Toyota. Many towable manuals and NO towable automatics.
Many 4-wheel drives are towable but again not all.
Nearly all-wheel-drives (the full time ones) are not towable. A wonderful exception is SUBARU! But only the manual shift ones.
If it needs to be your Daily Driver, the game changes. What else does it have to do?
In my opinion, the smaller, the lighter, the better. YES, most Class C "CAN" tow 5000-lbs. BUT, find a 2500-lb one and you'll be happier.
And again personally, I do not want a toad that has to be modified with a driveshaft disconnect or a transmission lube pump. And I don't want to mess with a dolly. That said, we LIKE manual shifts so that widens the field for us considerably.
