Ok well our experience is we LOVE it!! If it is even picked up to move it will shut off! No electricity is needed to operate unless you want the blower motor, BUT in the RV it really isn't needing the blower on. You can also use batteries. It does suck a lot of propane on high, but low we get decent hours on 2 small bottles or we run the hose adaptor extension you can purchase and feed out a window to a 20lb bottle and get a good 4-5 days out of it. Some RV's are designed so you can feed into your stove somewhere but ours isn't designed that way. Our old one probably would have worked that way.

Our furnace quit working so it is our back up until a repair person can come look at it. 2 weeks out so it is what we have. Furnace itself comes on, but blows cold and before you try being smart yes I have propane...lol I am not that blonde. Who knows maybe we have a bad regulator which when they bring a larger tank next week maybe we will find all our issues will be resolved as they will put another adapter on to work with the larger tank. Because the fridge also quit working. Sadly it can be a good $1100 repair or $1600 replacement. I do have a replacement part so if that is the issue we will be fine. Also have parts for the furnace but yeah I haven't clue one where to begin. So our backup Mr Heater will have to suffice for a couple of weeks.

Tips we have discovered however and should be written somewhere..... the first time trying to light it had me almost packing it up and taking it back to Murdochs as defective piece of you know what and a waste of my time and money. Once I calmed down I called the 800 number on the box instead, and ah ha of course the problem was simple, If you open the tank valves to quickly, it throws the safety in the heater and the heater wont light. I was told to close the tank valve and then opening it~ BINGO slow and steady solved the problem. (I did have to pop the hose off and back on at the tank to reset the safety). Now I know and thought I should document this since they don't in their instruction booklet.

the control knob is a little interesting. You have to push it all the way to light the pilot as alot of other heaters, hold it until the pilot takes hold, but you have to push it down only slightly to change temps. Just different until get the hang of it.

Basically bottom line.. No complaints now. Runs smooth, burns clean, no smell, does use a fair amount of propane on high but you get your propane worth you are burning out in no time and shutting it to low. Great heater. Recommended."
