So I have not bought a ROXOR yet, but I have been planing my "perfect build" once I get one. Anybody thought about installing a heater in theirs? I live in Michigan and when I get one I feel a heater would be a requirement on those -10 deg days. Thinking about something like the Flex-A-Lite Mojave Heater. If anybody has installed one I would appreciate any info on what worked good and what did not.
