Question Dolly Steering; Pivot Pan, Steering Axle, or Fixed Pan?

The Down side of a pivoting wheel model is that it is almost impossible to back up when attached to the RV, at least that is my experience. I have a Demco KarKaddy. My question is, I am considering leaving the pin and disables the steerable wheels (locks them in place), is there a reason (for general towing) that this should not be done? Thanks...

Having had two dollies, one a locally built one with a rotating pan and the other a KK-460 I can say the KK-460 is better, but heavier. Both dollies had surge brakes and worked OK, except for burning out the brakes in the first one on one pass west out of Jackson Hole! I've gone back to towing the Ody four down now since I can and got tired of moving the dolly around.

Yes, it shouldn't be done! Lots of stress on the dolly if the wheels can't turn to follow the MH!

Something needs to steer.

The dolly wheels.

A swivel pan that the tires sit in.

The cars front tires.

If nothing turns, you will be dragging the tires, sideways, around corners.

Then what is the issue with the dollys that do not have pivoting wheels, are they unsafe? And as far as dragging when turning, is that really an issue at a 5 to 30 turn? (Assuming rear wheels down)... Thanks

All dollies utilize some type of steering mechanism. It's either steerable wheels on the dolly or a pivot plate. In the case of a fixed wheel dolly the steering mechanism of the towed vehicle must be unlocked so they can turn.

The lack of, or the disabling of, a steering system would result in the dolly wheels being dragged through the turn. At the minimum tires would suffer extreme wear. It could also result in damage to the dolly frame, tongue or axle.

Navybuff,


For towing forward, like said above, something must pivot in the dolly/car set to make a turn, or tires will be scrubbing sideways...pivoting at the pan, dolly axle or car's front tires.

Use the stop pin on your KarKaddy in situations where the dolly is moved while unloaded (prevent crabbing or whipping) or while attempting to back if required.
Backing on a dolly CAN be done successfully if you back in a straight line...being VERY careful to not allow a turn to start for the car. Our "record" is 2 lengths of our RV when we were blocked-in at a fueling station.

The fixed pan style dolly has a few perks (lightweight with less parts and reduced risk of dolly/cardoor contact). It steers just like a flat towed car...car's front tires pivot to negotiate the turn.

Your KarKaddy is a wonderful dolly. And the other type dollies work well too.

Safe travels

Navybuff;

On my Acme dolly (no swivel plate) if I turn real sharp, I will pull the dolly wheels sideways a little bit. Its not a big deal, and doesn't happen often.

It won't do MACH 2, but I can get a sandwich and take a pee.
