Thanks for your note. I found a guy in Mesa, Arizona who owns a mobile RV service unit named Mitch Heuer (970) 948-9492 who did the oil change at my rig site for me. I simply ask the RV PARK owner for permission. Not a drop of oil was spilled and it was ultra convenient to to say the least, tons better than having to take the unit in to an RV service shop etc. As for Quartzite, at variuos rallys, there are a lot of these guys around doing all kinds of service work. I like getting this kind of service at the rig site. As for the BLM, THOSE FOLKS OUGHT TO be WORRIED WITH MORE THAN SOME GUY TRYING TO MAKE A LIVING BY PROVIDING A SERVICE. During prhibition you were not supposed to drink or sell alchohol either, how did that work out? By the way, mitch was very prompt and reliable, his service is called "GOLDEN MOBILE R.V. & DIESEL SERVICE". As for the BLM, high gas prices, not to mention a foul economy, one more reason not to vote for FIDEL OBAMA for President again.
