DenMar Enterprises

DenMar Enterprises is an RV maintenance and storage shop based in Coggon, Iowa, at 105 Railroad Street. It is a "veteran owned and operated, small town business" and it is new. You bring the RV to the shop. The site describes shop visits only, and it states no service area.

It works on RVs and campers, and the site names no RV brands. Its listed work covers winterizing, tank flush and sanitizing, holding tank service, water heater flush and descaling, air conditioning cleaning and replacement, roof reseal, roof component replacement, sealant inspection, vents, skylights, antennas, awnings, accessory installs and basic solar. It also offers indoor storage in a 7,000-square-foot facility with a concrete floor.

Several prices are published. A roof and sidewall sealant inspection is $75, and that fee counts toward your invoice if you hire it to reseal, though reseal cost varies by the items and the size and type of RV. Air conditioning service is $155 for the first unit and $125 for each additional unit. Holding tank service is $110 for the first tank and $80 for each additional tank. Hours are by appointment only, and no hourly rate is published, so ask for the full total before you drop off the rig.

Dennis Klouda, the owner, is a registered RV technician who trained in 2024 at the National RV Training Academy in Athens, Texas. The site also shows the RV Technician Association of America badge. Training is worth asking about when a fault is hard to see, such as a roof seam that leaks only in rain. The site gives no license, insurance or warranty statement, so ask about those before you approve work.

Google rates it 5 stars from 1 review. This is a good fit for an owner who can get the rig to Coggon, wants a roof inspection or winterizing with a published price, or needs indoor storage for an RV or camper.
