We are seriously looking at our next RV purchase to be a NH. We would like to get feedback from any NH owner that opted for the ductless mini split system in their Majestic. Good? Bad? Problems? Really any input would be helpful.

Thanks.

Lots of videos on YouTube

Ken, I don't pick my Majestic up until next month but went with the LG mini split systems. I've been in multiple NH coaches with the mini split. They are as close to a silent system as you can get. Owner's I've talked to are equally enthusiastic.

I went with three cassettes rather than the standard 2. System is 30,000 btu so 3 - 9,000btu cassettes really utilize the full power available. I've heard that at least one buyer, maybe Jack Mayer, did a 9,000 & 12,000 cassette.

Only caveat is that requires a 50amp, 240v hookup or generator since it is a 240 split phase system. You can't hook up to 30amp or 20amp power since those are don't provide split phase power. You could add a Victron AutoTransformer to get to split phase. If you are planning to do solar you can also setup a solar system for split phase using two Victron Inverters or a single Inverter with an AutoTransformer.

On the plus side they will provide heat down to about 10 degrees vs the typical 40 degree threshold of the standard air conditioner/heat pump.

The mini split is uses something like 1500-2000 watts of power in normal operation. See the YouTube's from Ben Goodwin, Tis The Destiny channel, where he talks about his solar system. You can see some of the Victron data graphs he shows to see the power draw while the mini split are running.

Just a followup note. While I was at the NH factory there was an owner's coach where the owner had requested to see if they could retrofit the LG Mini Split to their 2 year old Majestic. Might be possible?

I have a 240v mini split in my Teton. I installed a step up/down transformer and it runs on 120v service now. Dis this so I can run on small inverter generator

Off topic but do you plan on using your exiting dully to pull the NH? am also considering a NH or Spacecraft and am looking at the Ram 5500 and adding either an air suspension or Liquid springs

Depends on the rig we would choose. If we needed to upgrade to a F450, we would. Otherwise our F350 can pull up to 28K gvwr.

I had an 11 450. It was a real nice truck and pulled our 42' 5th wheel with ease. It just couldn't stay out of the shop unfortunately

ghaynes754 · 08-05-2022, 09:27 AM

Ken what is the actual payload that you have available in the F350? Depending on coach version and length pin weights can be in the 3500 to the mid 5000# range. Not many 350's will have that kind of payload available. Weight to be towed might be fine but not payload in the truck. Something to consider.

We will cross that bridge if we get to that point. If we need to get another truck, we will.

I was looking at the Ram 5500 but I would want to upgrade to either Liquid Springs or an Air Ride for when we are not towing. The NH is heavy on pin weight and I want the 5500 for the chassis and breaks.

ghaynes754 · 08-08-2022, 07:11 AM

Lenny, I have Kelderman Air Ride front and rear on mine. It is my daily driver and rides nice when not towing and excellent while towing my Majestic. I drove a stock 5500 that was on a dealer lot, still no bed, and it was a tooth filling shaking ride.

MtCamper · 08-08-2022, 07:20 AM

WOW, that was a good thread hi-jack. I hit this thread to see about an RV mini-split. I've thought they had the potential to be the wave of the future, sorta like the 12v refers. Any more feedback on the minis?
