[Larry & Diane]

Welcome aboard Chillnchick, soon
you will hear from all the great folks on this site and their knowledge is
impressive indeed. You may want to list your info in a tag line so that
all will know what year, type and converter your bus is. And don’t worry about
any stupid questions they have all been asked many times over (mostly by me!) so ask
away and like Jon says you may even get a correct answer!

Most of our buses are all electric so
that’s to be expected with yours too although some may be different depending on your converter. The AC equipment I
think you are talking about in the bay area is called OTR (over the road) air.
That’s the AC that keeps you cool while you are driving. Once stopped and are
plugged in or running your generator (depending on your converter again) you may have
either Roof top air units or Cruisair air. Cruisair air is units are usually located behind the
front bumper (it folds down) and possibly another unit located mid-ship
(accessed though another bay). Your Cruisair airs and Roof airs keep you cool (or
hot with the heat strips) while you are parked.

They say that the learning curve on
a Prevo is straight up and that’s about right. Keep reading the postings on
this site, you’ve found the right place.

Welcome to PC…

Our experts should be online to help you shortly… can you please put in the conversion of your Prevost as each converter does things differently..

Generally speaking you can run your basement a/cs while plugged in or on the generator… We need to know more info on your bus before we can really help you out.

It sounds like you may have cruisair units which are great units but do need to be serviced regularly, filters cleaned etc.

You may also have an RVAC unit which will also run from your power pole or generator.

You can turn them on and see what happens.

Normally the seller would show you how operate everything in your coach and not leave it up to you to figure it out, I find that somewhat disturbing.

Please let us know who converted your coach.

Thanks, Diane

thank you so much. We have a 1987 prevost Le mirage? 8v92 Detroit with Allison transmission. We haven’t been able to find out who converted it only on the paperwork it says car? Sorry we are totally newbies! I will be playing with the ace this weekend while plugged in so I can give you more info after that. Currently it is at its campsite so I can’t pop out and look. When we bought it, the seller was an older gentleman who had only used it a couple of times. We are up in Canada and bought it here so if there is a way someone can loook up vin numbers to get more information please let Mr know! I value your opinion. And can’t wait to be as knowledgeable about my coach as you all are about yours!

Fred…

Is there a way that you can post some pictures of your electrical panel and the bays with the a/cs…. also you may have a/cs behind your front bumper.. no way to guess… does your electrical panel appear to have breakers that say a/c fwd or a/c aft anythingo at all ??

Any info might help !!

All coaches, regardless of converter were designed to operate quite well on shore power. It helps answer your questions more accurately if we know your coach’s converter. Your 87 vintage coach might not have ever had roof airs because at that time most if not all converters were using Cruise Airs, typically three per coach.

You should be able to run at least 2 on shore power plus use most all other electric devices needed for comfort. You might have to select 2 that are on separate legs of the 50 amp service (typically the front and rear units) so you can use the stove or microwave or HW heater or lights etc.

One concern which is going to affect the accuracy of answers is the history of upgrades or changes to the coach. Typically in 1987 coaches had converters, a manually operated inverter to have a limited amount of 120VAC power when dry camping, and limited battery power. Through the years owners may have modified the electrical system(s) adding inverter/chargers and modifying what and how devices were run when using various power sources so you need to tell us not only about your converter but what if any mods have been done.

Don’t be afraid if you are not aware of how your coach is set up. Every single one of the Prevost enthusiasts on this site were newbys at one time and they had to learn about their coach also. We are all still learning.

Post photos if you don’t know what a device is. Post photos of the electrical panel. Once we know who converted the coach and how it is set up by seeing the various devices we will answer every one of your questions, and some answers may even be correct.

Four responders so far. All Liberty owners. Just reinforces the decision we made to buy a Liberty.

Good luck to the OP with his problem.
