Running fridge on generator

Well I have been running on propane, so that rules out that problem, the TC is brand new also checked the flues, no blockage, the only time it heats up is when we are moving, when stopped the fridge works like a charm tried the trap in the drip tube, also tried plugging one end in case it was sucking the cold air out. Narcodog when you say you put fans in the fridge compartment are you talking about the outside where the burner and flu are. As for the flame being blown out when you stop and open the fridge compartment the tubes at the bottom are hot running up to the boiler but the boiler doesn't feel real hot though but don't know if it should be that hot it's definitly warm though, as I said it cools great when stopped. Also even when the out side temps are in the 70's it still raises the temps in the fridge but usually only into the high 40's, weird problem though because it only happens when moving and you would think that there is enough air flow with the wind blowing in through the vents to move the air through the flues. tried blocking the bottom vents in case the flam was being blown out still no go, even though that worked a bit but the outside temps were in the 60's, as soon as they got up into the 70's doesn't matter what I do the temps still rise, thats why I thought about the generator, no flame to blow out, even thought about going to a threeway fridge and run with a inverter and the genny.
