Re: diesel pusher maintenance
When I bought my coach all I could really get was a call from the mech. Who could say "yup all up to date". Well over the next a little over a year I went from one end to the other. Trans. with Transynd(SP) the only fluid now for the 3000and two filters, the fuel filters(I have two)and carry a spare each, Anti freeze(at least have this checked for PH(one of the leading eng. looses is to acid eating the motor) Air dryer filters if you have one(one of the things that gets skipped alot), Change the Gen oil, and filter, rear end oil front bearings mine are oil bath, belts and hoses as mine were 10 years old, Air filter with cleanable aftermarket one( not a lot more $$$ than a just replace), Although mine is a Cat motor your should need the same. Also check tire dot date its on the tire 5-7 years max tobe safe, I just replaced mine at 7 and they looked like new. Check start batteries 5 years or so and be suspect, easier to get them now and shop around than at goober's station at twice the price. House batteries check hydrometer on each cell, not quite as needed because they go out slowly, kinda give warning and there are lots of places to get them.
As to the motor pulling the load YES it will, it's has a bit more torque and same HP as mine and I tow about twice the weight you will be, trailer and four runner on the trailer)
Good traveling and see you on the road.
