Ventana AC question

I'm looking at a 2018 Ventana 4037. It has two 15K AC units. If that enough for those of us that live in the South?

Thanks, John

We have had no problems in South Florida. Haven’t tried Bullhead City, AZ during the summertime yet.

Ours optioned the fiberglass roof and R19 polar pak insulation in the roof for 2016. We also use MagneShades on the front windows...and awnings on the Driver’s side windows. These all help.

2 are fine but 3-5 sure would be nice

You just have to understand as with any coach the glass is not your friend. Shades need to be down and stay ahead of the heat with cooling. Just like a house. Once you learn your coach and thermistor location considerations ie keep the bedroom door near closed so the better cooling from the back doesn’t trick your forward zone thermistor.

I too use magne shades.

Depends...

If it is 100* or more and you are out in the open, you will be challenged. A few things that will help...

1. Outside windshield covers. Mucho better than sun blocks on the inside.

2. Use awnings as much as possible.

3. Try to control the direction you park. There are some differences in opinion but I think the best direction to be pointed is to the South or even better South East. That allows me to deploy my big awning toward the sun and shade the side of the coach in the hottest part of the day.

4. I prefer to lock the AC fans on high as the morning heat starts setting in.

That being said, my 43' DSDP is OK in temps up to 100* for the most part. A 40' coach should have an easier time.

We have three 15k units (two are heat pump). Sure is nice on those days approaching or exceeding 100 degrees to have ample cooling capacity. Plus the third unit provides redundancy is case one fails.

Previous coach was 37' with two units. Did not keep up on those really hot days.

I definitely want three units on any future coach.

Can you even option 3 AC units on a 40' DSDP? The 2017 & 2018 Brochures don't show that as a restriction but previously I don't think you could.

That does open up some issues regarding front axle loading with the extra AC and larger generator. I would put a word of caution out on that issue if it is possible.

I do like the idea of 3 AC units if it works out simply for redundancy. Having lost 1 unit in early summer taught me that lesson.

3 is not an option on the Ventana (yet). I don't think they ever will on a 40. However, in my recent trip to Newmar land someone had a MADP there (40ft) that paid to add a 3rd unit so it's possible (most likely). I think he said around $3K but I don't think it's needed. 2 works fine. Just don't heat your coach to 115 and then expect 74 in an hour with the shades up.

I have two 15k units on my 43 footer and it has always kept me cool. However I've never camped in Death Valley in mid summer. Use the above suggestions and you should be okay.

I've checked and they say no go on three for the 40' and below. It's an option on the 43' Ventana. I really don't get why they don't allow it as an option on 40', since they do on 43'.

My thinking is that it is part and parcel that they upsize the generator. The combination of the weight of the extra AC and the heavier generator creates more of a potential for the front axle to be maxed out before you can load it for reasonable use.

Except I can't find any evidence that they go to the 10k generator with three units on the 43' Ventana. I need to reach out and find out. On the order form, it simply says three 15k units with energy management system. Nothing I have found indicates that the 43' or the three AC unit option moves you to a bigger generator.

We have had 39' fivers and a 37' MH with 2 airs. They just could not keep up. Generally speaking we could knock 15 degrees off in really hot areas, for example if it was 95 outside we could possibly get it down to 80 inside.

When we were looking at DP's that was one of our requirements, it had to have 3 air units no matter what. I guess you just have to ask yourself is it worth jumping up to a Ventana 43' floor plan?

My ordered Ventana 4369 is coming with the 3 A/C option, and they did NOT change the generator.
