Jason,
If you're ever up Denver way with that rig stop by. I have some 4x4s that Jiffy Lube doesn't know how to service. I always have to go down under with them and now I have a 6x6 and some trailers! These kids they hire can't concieve that a clutch linkage or steering nuckles would need service. They can't find books on a '69 Bronco, what would they do with a '66 Kaiser Jeep M109?
You might be able to start a mobile lube service. You could go coast to coast and see the country! Just about the time you make it around it would be time for the next lube. It would be like painting a battleship; when you finish at one end, you start over at the other.
