I try to do as much maintenance/repair as I can on my motorhome. I was on the road and when ever I stopped, I noticed a very small puddle of oil on driver side just a bit back from the front bumper. So I have on oil leak. No where to do the repairs myself, so went to GOM. They diagnosed a bad oil separator and said the driver side boost hose assembly would need to be replaced as well. They replaced both parts: parts and labor = $1,260.00
I also had them change the engine oil and filter which I provided. $126.00 for labor, ouch!
These guys are independents, but not less expensive than MB. Nice people, nice shop and a lift that could handle my 23.5' long Winnebago View. I would go here again in an emergency if I couldn't find another independent in Tucson to try. I avoid MB dealers.
