Onan 7500QD Gremlins
Genny runs great while the coach is stationary, but shuts down when moving down the road. Throwing a code 33, excessive coolant temp or low coolant but there is plenty of coolant and using my index...

If you decide to get inside the generator to R/R the temp sensor, just heat it a little bit with a propane torch, then spray it with some good penetrating spray (I used Deep Creep) and it will come out easily.
Also, at 3,000 hours, if you already have it apart, I would replace the belt, coolant hoses, the T stat, adjust the valves, and get the radiator cleaned and checked.
