We have a 2015 Cyclone 4200 and wish to run the generator on hot days while towing to keep the trailer cooled down. The generator will not run long. We had a 2011 cyclone with the same generator I believe it always would run fine while towing. Does anyone know if it is designed to be able to run while towing?
No reason why it shouldn't.
These gens run leaner then they ever have. So it might be possible that at highway speeds the gen is running too lean if there is any additional air being pushed in.
Have you checked the fuel pump? Fuel filter?
There have been a couple of instances where people have added a second pump back by the tank.
You could also check your fuel line. Ours was pinched behind the generator and was causing run problems.
I ran our gen frequently while on the road for the same reasons. Seldom had problems.
