I thought it was a cop out too! It has been very frustrating. The last time I dropped the trailer at the dealer, (a differenct dealer this time), I also got the manufacturers number and called them as well. They are finally going to work together to see about solving.

I didn't think about getting the furnace manufacturer involved. I'll mention that to them too.

I'll also have the check DC voltage.

The prior dealers didn't do much, I have high hopes for this new one and with the suggestions here, maybe this can get solved.

Just had the same problem. Dealer replaced the propane regulator and everything works fine now. He said that the regulator had reduced the flow too much for normal operation, but allowed some flow which allowed intermittent use of some, but not all LP appliances.

Have your dealer check for the high limit switch.

When it is not too cold out the furnace will cycle on and off enough that it does not reach the temp the switch is set for.

When it is cold and the furnace runs a lot it may be tripping the high limit switch. (Overheating)

If the temp of the switch is too low it will cause that problem.

I had a problem with my furnace not lighting after the first cycle. I found the solution by accident. While standing out side I was peering in the air intake with my hands cupped on each side of the vent while I hand my wife turn on the furnace and it would light every time. It was getting to much air.
Dealer adjustment fix the problem

My 2012 Montana High Country did that the day after I brought it home from the dealer... It worked fine at the dealer and intermittently after that.

It has an Atwood furnace in it where if you take off the cover to expose the curcuit board it will flash the error codes. The furnace manual will have the explaination what the error is in relation to the number of flashes.

Turned out to be a defective curcuit board and was replaced by a mobile repair on site.

ON EDIT: The mobile guy had a curcuit board tester with him and when he tested the board it would work several times before failing then work again a couple more times. I haven't had a problem since he changed it out.
