2nd AC unit worth it?

[leggy]

We have a 38ft Grand design reflection. In the three years of using it the AC never seems to keep up when in site that's full sun, which happens more than I would like. Thinking about putting a 2nd unit in front bedroom, already wired according to sticker in hatch. Looking for thoughts before we pull the trigger.
Thanks

We added a 2nd AC to our 34' 5er a few weeks back. We chose to go with the Coleman Mach 8 (low profile) 15K ducted w/ thermostat. It is a little louder on the outside than the Dometic Brisk Air II that came with the rig, but it is ultra-quiet on the inside. The difference in cost between the 13.5K and 15K is minimal, so we went with the larger one. It makes a monumental difference in the cooling efficiency of our rig.

I would highly recommend the Coleman Mach 8 like we got. It blows hard and cool and truly is whisper quiet.

We didn't struggle with removing the sealant around the vent opening. I just cut the roof membrane along the edges of the sealant and laid down 4 strips of eterna-bond tape. The roof membrane wasn't glued down there anyway.

I wouldn't have a TT or 5Ver without a second AC.

I have a 303RLS and we negotiated price based on installing the front bedroom AC. Get the one with the thermostat - but make sure that the thermostat is not installed in the path of the cool air flow. Definitely need it camping in the Florida summers.

Yes, it is worth it, we also have two. Get the second AC (low profile) and you will be happier.

My first TT was 33 feet, and was prepped for a 2nd ac. I should have bought one before leaving the lot. The following summer was brutal. My new TT is 37.8 feet with a 2nd ac. While I haven't camped in 100 degree weather yet, it was 90 degrees this past weekend and no shade. We kept the inside temps at meat locker levels.

A second AC unit definitely worth it.

Replacing the Magic Fan with the smallest non-ducted unit available is the only way to cool the bedroom of a 35' Titanium. The duct above the bathroom ceiling (the only feed to the bedroom) is 2" tall by 7" wide. No way!

Last July we came back from Yosemite across Arizona, New Mexico, and Texas. Without the second air we would have had to sleep on the (comfortable for only small children) sleeper sofa to get the LR air.

SAD it came with one!!! YUP two is a minimum on a larger RV. I vote for three!!!

We have a 35ft. motorhome with ducted air and added a Atwood Air Command 13,500 BTU non-ducted Air Conditioner. We spend a lot of time in Palm Desert and the River. It makes a huge difference having both airs running.

I have 3 A/C and there's times, in triple digits, when they all have a hard time keeping us cool.

I rarely camp anywhere when one AC is required.

We have a 33' Reflection 303rls with 2 air units. The second unit is very nice when you pull into a camp site and it is 95* and everything in the unit is hot. We turn both on at first and it really cools down quick. After the initial cool down one unit works great even in the mid 90's. When sleeping running only the living area AC is very quiet and the ducted AC keeps the bedroom just right.

My first fifth wheel had 1 @ 15K, and 1 at 13.5.. I was in heaven..... My 2nd fifth wheel had 2 @ 15K.... How could it get better??? My newest fifth wheel has 3 15k...... What a great thing ! ! !

I will never have a large fifth wheel without a minimum of 2 at 15K....

Shocking a 38' rig didn't come with 2 units.

We had to do some management on really hot days with our single AC 28' 5er.
