Class B RV Repair in Denver, CO

Class B RV Repair in Denver, Colorado — Camper Van Specialists

Class B camper vans have exploded in popularity among Denver's outdoor community, and for good reason — their size makes them ideal for navigating Colorado's forest roads and mountain pass approaches that a 40-foot Class A cannot access. But that versatility comes with unique repair needs. Van conversions and factory Class B coaches based on Mercedes Sprinter, Ram ProMaster, and Ford Transit chassis face the full force of Denver's climate: UV-degraded rooftop fan seals, lithium battery systems that require careful temperature management in Colorado winters, and diesel heaters that must operate at altitude. We provide specialized mobile repair for all Class B platforms across the Denver metro.

Rooftop Fan, Vent, and Seal Repair

MaxxAir and Fan-Tastic (now Dometic) roof vents are the primary ventilation and cooling solution in most Class B coaches. The fan motor, lid lift arms, and rain sensor are all vulnerable to hail damage and UV degradation. After a Denver hailstorm, we often see cracked MaxxAir lids and bent lift arms that prevent the vent from closing properly — an immediate water entry risk. We carry replacement MaxxAir 6200K and Fan-Tastic 6000/7350 assemblies and can typically swap a damaged unit in 45 minutes. The roof seal around the vent base is inspected and reapplied at the same time to prevent moisture wicking between the vent flange and the roof sheet metal.

Webasto and Espar Diesel Heater Service

The Webasto Air Top 2000 STC and Espar Airtronic D2 are the two most common diesel heaters installed in Class B vans in the Denver market. At altitude, diesel heaters require altitude compensation programming — most units have an adjustable altitude parameter in their diagnostic software that must be set correctly for Denver's 5,280 feet. A heater running without altitude compensation may lock out on a fault code or produce incomplete combustion at high altitude. We carry the Webasto ThermoTest and Espar Ediabas diagnostic tools to read fault codes, perform altitude programming, and replace glow pins, fuel pumps, and combustion air blowers on-site.

Lithium Battery and Victron System Service for Vans

Denver's van conversion community is heavily invested in lithium battery systems — Battle Born, Dragonfly, and SOK batteries paired with Victron MultiPlus or Renogy inverter/chargers are extremely common builds. Below 32°F, lithium batteries must not be charged unless they have internal heating elements — a requirement that catches many van owners off guard during their first Denver winter. We configure Victron SmartShunt and BMV-712 battery monitors to set low-temperature charge cutoffs, install battery heating pads where needed, and troubleshoot Victron MPPT solar charge controllers that aren't producing expected output. Denver's high-altitude solar resource is exceptional — up to 300 watts per panel-day in summer — and a properly configured Victron system takes full advantage of it. Call Mobile RV Repair Denver CO and we'll bring your van's electrical system up to Colorado standards at your location.
