Answer to: purchasing a paccar engineYall dont forget about the Mack mp8. My KY tech tells me no work from warranty with them and thats a good sign. They seem to have all the bugs worked out. Plus they are rock solid on the road and very well built. I am waiting for a secondhand pinnacle with the M-drive to hit the market but alas there are none being traded in yet.
Answer to: Roof top air installationDick Gore RV In RICHMOND HILL GA Installed my penguin low profile unit. basically the unit was too light and noisy for the job. I should have gotten a Coleman roughneck or a heavy duty dometic .The vibrations wreck the coils unless they are reinforced . The cooling was excellent i think it was a 15000btu but am not sure. we were short on room underneath our fairings so had to go with the low profile unit. I have since gone back to the true and tried method of using a portable room air conditioner run off my generator. $300 and lowes staff helped to lift it behind my passenger seat. quiet cool and cheap. The problem with this unit is it takes up much needed space in the cab.
