Towing with a tow dolly
Bought a new (to me) motorhome over the weekend--82 Bluebird Wanderlodge. Plan to tow a car on some trips. Since neither MB is towable with 4 wheels down without some modification, I'm considering towing rear wheels up on a tow dolly. Anyone have any experience with this? Are tow dollys too much of a headache? Would it be better to buy an older manual tranny vehicle and tow with a tow bar?

Tow your MB backwards :rolleyes:

I tried to dolly a W114 sedan backward behind a 2006 Dodge quad cab 1500 short bed 2wd and scared the s**t out of myself...the tail kept trying to wag the dog. Now, with a larger tow vehicle, I suspect you wouldn't notice the sensation as much, but the car being pulled may still get squirrely.

Do you think it was a result of more weight on the front wheels of the car than weight on the dolly, or just the relative weights of the vehicles involved? I know things get squirrely if a traditional trailer gets tail heavy but I don't know if the same thing happens with a dolly.

I suspect that it wouldn't have been so bad if the weight had been over the dolly wheels. It was a really strange effect though, because the back of the truck was moving around, like its butt was wiggling. I guy I work with dollied a Suburban backward behind a fullsize GMC truck, and said that every time the Suburban started moving around, he just stood on the gas and accelerated out of the wiggling motion. He's a braver soul than I. I would just let the thing coast down to a speed that it stopped wiggling around.

Weight has little to do with it. An automobile's steering geometry is all wrong to be pulled backwards with the front wheels on the ground. The caster angle and amount of steering 'trail' that makes the steering natually want to center while rolling forward causes it to become intrinsically unstable moving in reverse.
Think about how responsive your steering is when attempting to back up at high speed. Now imagine doing it at 70mph. :eek: :eek: :eek: All about caster from Wikipedia Quote:

It doesn't sound like a wise idea. I thought the responsiveness of the steering when reversing was a result of having the turning wheels in the back instead of the front.

If the steering was properly locked with the wheels pointing dead ahead, you might be fine with it..........but you might also eat some tires if the front wheels were at a slight angle to the direction of travel. |

Tow a trailer instead of a dolly. It is not easy to back the trailer but it can be done. Backing a short trailer behind a long vehicle is especially tricky. Backing the dolly is by chance only and when you make a mistake, things break.
