We just recently purchased our 2005 Dutchmen Class C RV and will be heading out on our first shakedown trip tomorrow. To prepare for our first trip I've been reviewing the owners manual in great detail and the tire inflation process they recommend is something I've never heard of before and so now I'm wondering how everyone else maintains their proper tire inflation. The owners manual says "tire pressure must be performed by personnel trained, supervised and equiped according to OSHA regulations. For example, during any procedure involving tire inflation, the technician must utilize a remote inflation device, and insure that all persons are clear of the trajectory area." If that's the case, I don't see how anyone could check and adjust their tire inflation. Is anyone actually doing this, or are most of you checking and adjusting your tire pressure yourselves?
