We just ordered a new 40 Allegro Bus and had the option of a third ac unit. I comes with a larger gen set (10kw) for about $2k. Do I need the third unit. We don't spend any time in the desert or summer in Arizona.

In the south it is hard to have too much AC on an RV. I would add the 3rd A/C unit if it were mine. I like to be warm in the winter and cool in the summer.

You can't have too much A/C here in the south. I'd rather have it and not need it than need it and not have it. I can always turn off the excess, but I can't crank up what's not there!

I have not had my rig in the desert nor in Arizona, but RVs heat up pretty easily and there have been many times I wish I had 3 AC units.

DITTO
you can never have to much a/c cooling

i wish we had three.

For $2000 you get upgraded to a 10KW genset and one additional a/c? I assure you, you will kick yourself for not getting that upgrade.

The problem is it adds almost 500 lbs to the coach; the 10kw weights 350 lbs more than the 8kw (its a much bigger engine) and the additional ac weights another 100+ lbs. The 350llbs is hanging out front, and the 100 is on the roof. I'm not sure how close the front end is to the 14600 capacity.
Thanks to all on your insight on this.

Bear in mind as well that it's not just the high ambient temperature areas where additional A/C will come in handy. In addition to the ambient temperature (sensible heat load), the A/C also has to dehumidify the air (latent heat load). This means that an A/C system might be working harder in 90 degree ambient temperatures with an 85% relative humidity than it would in Arizona with a 110 degree ambient and 5% relative humidity.

Of course, those of us on the Gulf Coast feel like we have to deal with 100+ degree ambients and 100% relative humidity (only a slight exaggeration!

), so we look at lots of A/C as a constitutional right!

Bob Tiffin isn't going to offer an option that will get you close to the weight limit.

And like Rusty said...its our "state" constitutional right. The other one apparently has kinda gone out the window.

Call Tiffin directly and ask to speak with Bob. He will tell you the truth. Don't depend on what some salesman tells you.

If I were buying I would go for the 3rd unit just to get the 10kw genset and I wouldn't be all that concerned about the extra weight which is minuscule when compared to the total coach weight, however, it's your coach and your Call.

Best of luck with your decision and congratulations on your new coach, Jim

My vote would also be to play it safe and get the third air.

I have a friend with a Tiffin 44 footer and he has 3 a/c's.....also have a friend who is in calfornia now with a 40 ft with 2 a/c's and he is suffering.......
