Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.


We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!

Diesel Pusher "Engine Air Conditioning"

Some where back, I heard that you can't rely on the engine air conditioning system to cool enough to make any difference in the temperature of the coach...any truth to it?  or, do you have to run the generator while on the road to run the roof air?  If the engine air is to work ok, has any one re-charged their system?

We have a 40' DP and have never used the generator and roof AC while driving, except when traveling in 98* temps with our three grandkids strapped on the sofa.  Only a few other times, driving west, late in the afternoon, have we been close to running the roof AC.

Happy trails,
Mary

I know we use the engine a/c when traveling and so far have not had to run the generator for roof air. We don't normally travel very late in the day so we aren't on the road during the hottest part of the day. I don't like getting to parks after dark and trying to setup in strange surroundings. We do our 200 or 300 miles a day and then find a place to hookup. Then if needed we turn on the roof a/c's. We're retired and in no hurry to get any place :)

The dash air conditioning has been enough for us most of the time in both our previous gas motorhome (35') and our present diesel pusher (40'). But we have run the generator and roof air in both of them when it was really, really hot (95 plus) mostly to cool off the rear of the motorhome. We have also needed to run the generator and roof air when the dash air conditioner was broken. Yes, we have had to fix the dash air on both motorhomes during the time we owned them.

Joel, we have pretty much the same scenario as Bill, first a gas and now a 40 DP. But here is a little trick that I picked up from one of my RV Macgyver buddy's. Buy a shower curtain rod and use what ever you like for the curtain part and hang it just behind the front seats and it will hold the cold air towards the front better and will do the same thing for the heat when needed. I'm sure Bill has done the math on running the dash air as apposed to the gen set and roof air and I'd bet it's cheaper to run the gen set and roof air while driving. Hope this helps. Gummy
