I just viewed a picture of this RV is this something you plan on doing or an RV repair shop doing this?

I plan on doing it I have all the means to do so just dont know easiest way to do it
Expert:  Robert replied 8 years ago.


Normally in the shop we would use the lifts on all four tires, raise the rv, support the engine and trans. and raise the RV away from the engine. I do have some directions on removal however this is and older vintage and may not be very helpful. IF you like I can send the procedures, IF they are not what you are looking for I can opt out for another expert. I think you will know after reading over them. Just to verify is this a 5.7L?


Customer: replied 8 years ago.
No it is a 7.4

This is the information on this vintage. IF you feel it is not enough information I will opt out for another expert, I want you to be satsfied with the information you are getting. I hope this does help.
