You can tow your s10 pickup on a car dolly. You must back the rear wheels into the wheel supports so that the rear wheels do not rotate while in motion. Position the steering wheel to center position and tow away. I've towed mine across 4 states with no problem.

It is not advisable to tow a full size pickup (or any other rear wheel drive vehicle) behind a motorhome, unless all 4 wheels are on a dolly. This can be acomplished though by a drive-shaft disconnect. These are quite expensive.
Manual will work, auto will not.
