Well, living in FLA, it gets hot here. I have a '16 29ME and I guess I'm in the minority here. We have been camping several times with daytime temps in the 90's. First of all, I keep the MCD shades down on ALL windows/doors. I got the Heatshield window shades for the front and side windows of the cab (game changer!). While I'm getting the coach ready, I crank up the fantastic fan in the bedroom and the bath fan to get rid of the 97 degree air inside. Then, I fire up the genset, A/C, and fridge for the trip. I also open the air dumps on the A/C unit to get max air into the main part of the coach. I crank the A/C on in the cab which works great. Once I feel that most of the hot air is out of the coach, I shut off the fans and head out. By the time I get to my destination, the inside is cold. I think the key is getting the hot air out (fans) and using the genset as you are heading to your destination. I have no complaints about cooling my RV, and this was one of my biggest concerns as I live in FLA and will be in South Florida and the FLA Keys most of the time. I hope this helps, as I think getting the heat out of the coach (fans) and cooling it ASAP might help.

Wish I had seen or known of these shades a few weeks ago. About to head out soon and heat is a struggle for our 32' long rig with a single 15k AC unit.

I like the blow out the hot air idea.

More thanks

Good tips here , thanks again!

Got the sun shields for the Windows and will be heading out later this week. Going into Wyoming which can get pretty warm! We'll be using the information here for sure!

Will let everyone know how it goes.

Thanks again!

We have a 2016 Greyhawk 31FS. The air conditioner is not keeping us cool at all. Works great at night. Yesterday, it was 88 degrees outside and 87 degrees inside. The next 24 hours, we got the RV really cold at night, kept all the windows covered, isolated the drivers cab, blocked the cab windshield and windows. Still not comfortable and not a pleasant way to spend your vacation in a dark box. Going back to dealership the first of the week. It's only 8 weeks old.

Almost every year, we venture to the Colorado River at Blythe, California for the dove season opener. It's Sept 1, so often near Labor Day weekend, and it's the hottest time of the year. Also humid. Often, temps reach 115 mid-day, and humidity is around 60% or more. We learned early on that we needed the foil covered bubble-wrap window covers on all openings that could allow sunlight into the RV, and that any shade we could find was helpful. We had a single 13.5k air conditioner in our old 26 ft toy hauler, and it cooled very well after the initial two or three hours. AC ran all weekend long, and it cycled also. We did find, however, that it was best if we gradually turned down the setting on the thermostat in that first half day.

They work as advertised as far as heat reflection goes.

Word of caution though; the velcro adhesive that marries to the coach walls I guess got too hot and it started to pull a little. Not happy with that, though I suppose I could go the snap fastner route. Just not keen on drilling into the fiberglass. Really at all.

I will call the company up tomorrow to see what they have to say. The protectors DO work though, velcro aside. My coach stayed at 74 degrees in full sun / no shade when it was 88 degrees out at Castaways, MD.

We're plugged into Shore Power but today it's high 90's and direct sun on our 31FK. AC is keeping it 83, 84* inside, so it's doing OK.

Not great, but OK.

We've got the shades pulled down too.

Regular white window shades don't cut it. You need something that actually reflects both light and heat at maximum level. Something that won't allow heat transfer to the inside of the box. I used this material Reflectix 16 in. x 25 ft. Double Reflective Insulation with Staple Tab-ST16025 - The Home Depot
to cut out exact matches to each window, and use the existing day/night shades to keep it in place. Edges are finished with foil tape. This does an adequate job of forcing most of the heat to remain outside the window. If you really want to do a good job, and don't mind sticky stuff all over your outside window frames, you can make these to cover the whole window frame and glass, and velcro them to the outside, so even the window frame is cooler. There are disadvantages, however. You have to pull the covers aside to see outside, the lights will likely stay on a lot inside the box, and its sometimes a pain to keep them from falling out of the window frame if you don't stick them with velcro. But if it's hot enough, you'll find a way.

2017 Grayhawk 29 MV

Sure wish I would have seen these post before last week. I purchased a new 2017 Grayhawk 29 MV. Before we left the dealership we voiced concerns about the AC not cooling. We were told it takes time to cool down the coach. Brought it home and plugged it in. Temp outside was 92. Temp inside was 88. I live in Louisiana and if I can't use my new motorhome when the temp is above 80 degrees then I will not be going camping very often.
Bringing it back to the dealership next week but from what I'm reading I think I may have made a BIG mistake. Why don't they tell us these things before we purchase something they know won't work in our climate?

We have a 17' Redhawk 29xk... The AC is the same as well. I knew what I was getting into and plan to install a 2nd AC early next year via a second power plug. The dealer won't do such an install but gave me info on some that will. After talking to the tech and researching it, I think I'll install it myself. We're in Dallas so the temps are def an issue with a single AC and a 31' MH.
