Since Carl's Acre's of Trailers closed in 2013 there has been no one who could or would work on Coleman trailers. I have had my routine work done by a local (to me) shop in Torrance Meyer's RV and they have been fine for brakes, bearings, and misc. parts but forget it if you have any pop up specific issues. I needed some help with the lift system on my MTM 2008 Niagara and while all of the help on this site is fantastic I just did not have the time (I travel for work every week) and didn't want to screw it up. So I have 2 words for anyone looking for help "Custom RV" in Ontario, California. They are leasing the old Carl's place and hired some of the old mechanics and these folks are friendly, fair and did everything the first time correctly. I can't say enough good things about the crew and the service, George, their Coleman mechanic, fixed a couple of items I didn't know were broken and didn't charge me.
