Almost any truck that is four wheel drive and has a Neutral position in the transfer case will be towable four down. Always check the Owners Manual for recreational towing instructions.
Of course, weight is a consideration. Your motorhome likely has a towable weight rating of 5000 pounds. While this is a RATING, not a firm limit, exceeding that rating is not advisable.
IMO, the best towed vehicle is a Jeep Wrangler. I like the Unlimited for the longer wheelbase and better ride.
I do not know of any vehicle that is manufactured with a braking system for being towed. NSA makes the Ready Brute integrated towbar and braking system that does an excellent job according to all reports.
