Having now lived for close to a year with this wonderful Prevost Country Coach Motorhome there are two things I would implement if we ever have another GMC.
The first is the generator sits on four small air bags that greatly reduce both vibration and noise transmission. The bags sit between the generator mounts and the coach chassis. They are not very expensive and apparently readily available. They would be easy to plumb in either by T off one of the compressor/air tank outlets with check valve, or by adding another inexpensive 12vdc compressor just for that task. The air volume is quite low so even a small displacement compressor would work well. Plumb in an air pressure regulator so you can dial in the desired air pressure. Wire the compressor through a relay powered off the positive post on the gen coil. That way the compressor would come on only when the gen is running and only if the air pressure regulator called for air. Most of the time it would only run for a few minutes at initial gen start and then shut off once the air bags were inflated. One could also power a 120vac small compressor (think small trim nail gun compressor) off of the 120vac output from the generator with the same result.
The second idea taken from the Prevost also involves air. The Prevost uses small air bellows to tension the belts powering the side mounted engine cooling fan. With a simple to make bracket and a pulley to push on the belts, it looks like one of these could easily tension the alternator and/or AC belts. With the air off the belts would be slack enough to replace by hand with no tools. With air tensioning, belt squeak and stretch would automatically be compensated and replacing a broken belt would become an easy no-tool five minute job. The ones Prevost use cost less than $50.
