There are front wheel drive cars that can be towed on all wheels and there are also 4WD vehicles that can't. With most cars the determining thing is the transmission and with 4WD they must have a neutral position in the transfer case. The best way to know if your care can be towed on it's wheels is to look in the owner's manual under towing. But you are correct that the cost to set up to tow on the wheels isn't cheap. But a good dolly that has brakes isn't all that cheap either.
I'd wait, Uhaul will sell what you need, and fairly reasonable. The drop will matter, and without measurement, who knows. You could ask salesperson to go and measure, there is info on how to measure on uHaul website.
Probably less expensive to get your own. Hitch height is less critical with a dolly than with car-haulers or 4-down toads, but close to level is still the most desirable attitude. Motorhomes are typically fairly high and a drop-hitch is used, but you really need some clue as to the height. Adjustable hitches aren't infinite; they typically have a range of 4-6". Some motorhomes may be best with an an 8-10" drop, but an adjustable that can do that may be pricey. Think in terms of $250+. Etrailer.com has an 11" adjustable drop adapter for only $179 but you need to add a ball mount to that price.
Oh I see, I can't back up, even with a car on the dolley? Where I was going to park overnight before returning the dolly I think is a one way thing, have to back up to get out of there. I'll try to park where I can just pull through, don't want to unhitch.
With the trailer, you could back up.
Even if you were to use the trailer, backing up is not the easiest thing, especially when using a motorhome and with little or no previous experience.
I've not used a dolly, but in backing my flat-towed toad I find I first must be straight before backing, since not being straight causes almost instant veering off course. But by creeping very, very slowly I've backed over 10 feet. But it does take extreme caution to not cause problems.
The turning radius on a dolly is very short, and the slightest angular force can produce a significant change in angle of attack.
And even more if the tow vehicle was a motorhome.
But a trailer is relatively easy to back. Try that with a dolly or a 4-down toad behind a motorhome.
If you have never tried this in a very large convention center with booths set up and people everywhere you might not consider it easy. Have done it many times with a tow dolly. I would never consider it with a car 4 down. I have backed our RV with the car on the back 4 down for 10 or 15 feet many times. Chuck
