Engine replacement 1992-1995 Holiday Rambler Vacationer

It's a grunt job, will fit through front but you will work to do it and I would consider how much your time is worth compared to a pro. Cover the valves with towels to keep dirt out. I have done inframe overhaul on Cummins engine but that different. Biggest problem is getting the balance on the crane right and not dropping it. You gonna do a short block?
