||We have an 85 - 32' Winnebago Elandan on a Chevy P-30 chassis with an Onan 6.5 RV Genset. It has a long, narrow service door which barely provides enough room to check and fill the unit with oil. I need to change the oil filter, but can't seem to get the cooling shroud off and out of the service bay as it does not have enough clearance. Looking from underneath, it looks as if the unit is mounted on a 2'x3' steel pan, which is bolted to the truck. Can I unbolt and lower the steel pan to gain access to the generator? And if so, would the entire unit need to be supported, and would I need to unhook any wiring before doing so. The Winnebago manual is exceptionally light (as in zilch info) on generator maintenance, and the Onan manual is no help in this area as far as servicing the unit while on the truck. Has anyone had any experience with this setup. Any tips or pointers will be greatly appreciated.
