I drove by a Jiffy Lube in Albuquerque and saw that it had large entrance doors. I went in and asked about changing the oil and a lube job on my Class A gasser. They looked up my engine, saw that they stocked the filter and said bring it in. I drove over the pit and in a few minutes they had the oil changed and chassis lubed. It cost me the same as if I was a standard pic-up truck. Sometimes all you have to do is ask instead of making assumptions about whether or not a shop will change your oil.
