Keep Your RV Ready for the Road
Thurn's Sales LLC provides RV service in Bismarck with experienced technicians and warranty support for most brands.
Your RV sits through a North Dakota winter, and when you pull it out in spring, the water heater won't fire, the refrigerator runs warm, or the slide-out mechanism grinds instead of extending smoothly. Thurn's Sales LLC offers RV service in Bismarck with technicians who handle pre-season inspections, appliance repairs, and warranty work for most recreational vehicle brands. You bring your unit to a local shop instead of driving hours to an out-of-state facility or waiting weeks for a mobile technician to reach your area.
The service team works on travel trailers, fifth wheels, and motorhomes, addressing mechanical issues, plumbing leaks, electrical faults, and appliance failures that prevent safe or comfortable travel. The shop handles warranty claims directly, which means you coordinate repairs through one local contact rather than navigating manufacturer service networks on your own. Scheduling works best when you call ahead to describe the issue and confirm availability, especially during the weeks before camping season when service demand peaks.
Call Thurn's Sales LLC at (701) 240-3030 to discuss your RV service needs and schedule an appointment in Bismarck.

What Local Service Provides for RV Owners
When you bring your RV to Bismarck for service, the technicians inspect the systems you rely on during a trip, including propane lines, water pumps, slideouts, awnings, and electrical hookups. They test appliances, check for leaks, and verify that safety features such as carbon monoxide detectors and LP gas alarms function correctly. You receive a written summary of what was repaired, what requires monitoring, and what should be addressed before your next outing.
After the service, your water runs clear from all faucets, the furnace ignites without hesitation, and the refrigerator holds temperature on both electric and propane modes. The team has decades of combined experience with RV systems, which allows them to diagnose problems quickly and source parts through manufacturer networks or aftermarket suppliers. You avoid the guesswork of online tutorials and the risk of making a minor issue worse by attempting repairs without the right tools.
The shop serves customers before and after peak camping season, handling everything from winterization in fall to de-winterization and system checks in spring. If your unit develops a problem mid-season, you can schedule service without waiting for a spot at a distant repair facility. The service operates alongside the RV sales department, which means technicians are familiar with many of the units sold locally and can access service records for repeat customers.
You Probably Have a Few Questions About Service
RV owners often ask about timelines, costs, and what to do if something breaks while they're on the road, especially if they're new to RV ownership or dealing with an older unit.
What kinds of RV repairs does Thurn's Sales LLC handle?
The shop works on appliances, plumbing systems, electrical components, slideouts, awnings, and general mechanical issues across most RV brands. If a repair requires specialized manufacturer support, the team coordinates warranty claims and parts ordering on your behalf.
How long does RV service typically take?
Minor repairs such as a faulty water pump or thermostat replacement often finish within a day or two, while appliance replacements or structural work may take longer depending on parts availability. Calling ahead with details helps the shop estimate a timeline.
When should I bring my RV in for service?
You should schedule service before your first spring trip to address any issues that developed during storage, and again in fall to winterize the plumbing and prepare the unit for cold weather. Mid-season service works if something stops functioning correctly during a camping trip.
What happens if my RV needs warranty work in Bismarck?
Thurn's Sales LLC handles warranty claims for most RV brands, which means you bring the unit to the shop and the technicians coordinate with the manufacturer to approve and complete covered repairs. This keeps the process local and reduces delays.
What should I do if my RV breaks down while I'm traveling?
You call the shop to describe the problem, and the team advises whether it's safe to continue driving or if you need roadside assistance. If the issue can wait, you schedule service as soon as you return to Bismarck.

Fiberglass Repair
Fiberglass repairs on RV’s can make a big oopsie disappear.

Slide Out Repairs
It is important to check the caulking on the walls and roof of your camper routinely. It doesn’t take much time for water to rot out the floor of a slide or the main floor of the camper. These pics are from campers less than 5 years old. We can perform preventative maintenance sealing up your RV, or if it has gone this far, we can fix that too!
Water Damage Repairs
Water damage from the roof is common. We offer preventative re-sealing of the lap sealant, or if more work is needed, we can re-coat the whole roof with a silicone sealant to extend the life of the roof, or if the roof decking is soft or damaged, we can rebuild trusses, re-deck or make any other repairs necessary, and then put on a whole new roof membrane. We offer PVC and commercial TPO roofing membranes that will significantly outlast OEM products.
