Anyone with an RV should seriously consider a different heater, the Chinese one works a treat, now i have it if they were not available i would something similar, RV heaters can sure deliver a lot of heat but they use a lot of gas and really drain the batteries, as we are rarely on hook up this can be an issue, I have fitted a 100 L tank to reduce the times i need to visit a garage for LPG , i fitted the 15 L fuel tank underneath the RV this will do a weekend and I have been using heating oil so cheap heating. but the best thing is the increased comfort in the van compared to the on off cycle from the RV thermostat for the gas heating, when the temperature is reached it slows down but still produces heat unlike the RV when the temperature is reached there is a blast of cold air and the same on start up. the Chinese heater will be my main heat source and the original will be the back up. the latest chasson vans have water and heating from the diesel heater as standard.
