im planning on buying a 5th wheel camper and im just trying to figure out what i should do before i start pulling it?

what kind of mileage should i expect?

 

I would just service the trans, new filters and fluid. One of the most important things to do is to have your oil cooler checked, oil temp and coolant temp should never be more then 15deg apart, if it were me and the oil cooler has never been rebuilt I would do that and then add a coolant filter to prevent the oil cooler from clogging up again. If you have over 50k on the motor without a coolant filter then a oil cooler rebuild would be recommended. you might want to rethink your stack too, all that heat and soot won't be good for the front of your trailer.

 

that oil cooler has crossed my mind a time or two but have never done it. im not sure if it was ever dont either.

when i put the stack in i though ahead with it and made the up pipe the goes into the stack so i could just turn it 90 degrees to make it become a turn down.
