Some Happy Customers
“This is simply the best place in town to take your rig. They were not only open and honest with me, they took care of me with absolute grace in a stressful situation. If I can recommend any shop to anybody in town it’s here. They are the best, hands down. Thank you guys for all the work, patience and kindness you showed me! I will be in again soon for my maintenance!”Tia Stagg
“We had an overheating issue in our diesel pusher motorhome, and when I called RMD I was told to bring it right in. They analyzed the issue quickly. Kerry & team started the repair and got us back to our travels asap. We aren’t locals – we are from out of state. Made no difference to this team, they got us rolling again at a very fair price. I wish I could find others like this as we travel!”Eric Kaiser
“Awesome people, worked us in, did extra things that did need to be done. Got us back on the road faster than I anticipated!!Hasan Milon
