why would ford be the most used ,getting to back difficult.

I drove a 3500 based school bus last year, I have an E 450 rv. Really not much difference in getting up and going back. The newer 4500 we have are about the same. Have to move the seat back if you want free and easy access on both. I just leave it be as it is a PIA to have to readjust as you never get them in the same position it seems. Always 1 notch off. Same this year with a Thomas bus, can never seem to find the same position once the seat is moved. Thats why I want to find some electric seats for the rv.
