For a one-time-only trip, I might consider a tow dolly, only because of the cost of modifying the toad (towed) vehicle. In just about all other ways, the dolly is more inconvenient. There's the weight issue, there's having to find a place to put it while parked, and there's the load/unload process. Hooking up a four-down rig is faster and easier than loading a car onto a dolly and tying it down.

In either case, NEVER back up a four-down rig. As soon as the wheels turn to the side, you will immediately jack-knife the rig and possibly damage the tow-bar. It's possible to back up a dolly rig, if the connection between the car and the dolly is rigid (the car can't twist on the dolly). There's no way to do a four-down. And don't try to put someone in the car holding the wheel straight - that's a recipe for a broken wrist or worse.

For 95% of the RVs out there, if you get gas it will be a front engine, diesel will be a rear engine. Diesel rigs are heavier, carry more, more power for hills, etc. But they're bigger. The break point is somewhere in the mid-30s (feet, that is). Shorter will be gas, longer will be diesel. My personal preference is for diesel, because they have more carrying capacity. is a good site for all things RV-related.
