I thought most Georgetowns were based in the Ford F53 chassis.
But, the worst case scenario I read on one of these forums (maybe not Forest River) was an owner that could turn his seat around, HOWEVER.....his steering wheel was NOT directly dead centre of his driving seat.
Others have reported their seat cannot be moved far enough forward (if they're short in the legs) or far enough rearward (if they're long in the legs)
My driver's seat only turns a few inches past 90 degrees towards the interior, and the most comfortable position has the left arm rest in the up position and I use the steering wheel as my left arm rest.
Just gotta be careful not to honk the horn.
