Check reviews for your specific repair, not just the star average. Some shops handle multiple systems, so ask what they can do before you hitch up.
Shops that earn their stars
Rapid Diesel Repair leads with a 4.9 from 314 reviews and handles both mobile calls and A/C work, plus chassis and parts. Galaxy Campers also rates 4.9, from 127 reviews, and does warranty work, which matters if your rig is still covered. New View Glass focuses on roofs and holds a 4.9 from 48 reviews. Desert Rentals Unlimited sits at 4.7 and is open weekends, a rarity. Arrow Trailer Supplies has a 4.5 from 341 reviews and stocks parts, useful for DIY fixes. Affordable RV Repairs has only 2 reviews and a 2.5, so tread carefully.
Mobile vs. shop work
Two mobile techs serve Ontario, which can save you a tow. Mobile is great for A/C failures, slide-out issues, and simple diagnostics. But roof repairs often need a shop with a lift and dry space, so call New View Glass if water is coming in. For chassis or engine trouble, Rapid Diesel Repair's mobile service makes sense. Ask about travel fees and whether they carry common parts. If the part isn't on the truck, you might wait. Booking ahead helps in spring when everyone discovers their A/C died over winter.
