Gas fridge on the move?

I have a 98 Lance and it has always had trouble running on gas if speed is over ~50 mph as the flame gets blown out causing the check light to come on, otherwise it works great on gas. May have been your problem with a cross wind as you say it worked before. If it is failing while stationary could be something else. I had to replace my dometic control board after only 4 years with a dinosaur board and never had another problem. It would just shut off the gas solenoid 5 minutes to 4 hours triggering the check light. Thermocouple voltage tested fine. Was a common problem with this vintage.

I use the DC mode while on the high speed roads and am careful not to leave it on DC if the truck is not running. DC works fine on the road to maintain temperature if you have at least an 8 awg wire from truck to camper battery through a 40 amp circuit breaker and an isolator solenoid. Remember that it is not on continuously and cycles just like ac or gas mode. Always pre cool the frig a day before leaving on the trip.

All good advice. :)

Personally, while I generally precool my fridge and put already cold stuff in it and the freezer most of my destinations are < 3hrs away and I see no issue(s) with traveling with it off - things are not going to thaw out or get warm in the time it takes to travel and then get the fridge going/cooling again.

It should be noted that (decades ago now) Lance recognized the problem with running the fridge in DC mode (and/or charging from the truck) and invented the "Lance connector" to solve/deal with the issue.

Lance dealers would install 8AWG wire+solenoid+fuse connected to their 'special' 7-pin 'Lance connector' outfitted with 2x 8AWG wires and 5x 14AWG wires umbilical cord to the purchasers/owners Lance truck camper. Properly installed Lance campers have no issue running the refrige on DC or charging the house battery from the truck.
