Just in general...
Toad will follow RV in gradual maneuvers like a curve in the road
RV will force Toad to follow in sharp maneuvers like a tight corner or U-Turn
Now, let's use a Right Turn by the RV...
RV is steering Right, but the Rear Overhang swings LEFT...
RV straightens out, and Rear Overhang swings RIGHT...
But TOAD is still steering LEFT!!! If the steering geometry or something else (maybe electric steering) keeps it from coming back to center, you drag the front wheels of the Toad, Sideways...
Our first two toads were a Toyota Tercel (base model, manual transmission and manual steering) and a Mitsubishi Pickup (base, manual and manual)
We towed with a 24-ft Class C with only 158" wheelbase. It had a long rear overhang, and could turn pretty tight with its short wheelbase. On a hard right turn, the Tercel would get hard over and stay there. I left it unlocked so I could run back after I'd stopped, and center the steering!!! The pickup, on the other hand, never did that.
We have a Corolla and a Frontier now, manual shift, hydraulic power steering, and neither displays the problem. But... our 31-ft Class C with five more feet of wheelbase, needs a football field to do a U-Turn, so I don't think the toad steering is really being challenged.
