Looking for a vehicle to flat tow

Okay, so I’m still working on the master plan of getting an RV and now I think it would be great to get some kind of vehicle to take along with me. An old Jeep Wrangler has a certain amount of appeal, or something like it. I’m curious about the ins and outs of flat towing a vehicle. If it’s just a really bad idea, or if certain vehicles are great for towing, etc. I know that the vehicle we currently have cannot be flat towed. Any info would be appreciated. Thank you!

Just about any 4x4 that can be shifted into neutral at the transfer case is ideal. This is a good link to use for towing information and tow-able cars.
