Ill post what I "had".
We ran the mini splits for about 2 months. After 2500 or so miles the lines kept coming loose and we pulled them and went to roof airs.
When they worked they were great. Very quiet, kept the bus dry and made for a clean roofline. But in the end, as we are fulltiming- I didn't have time to screw around with constantly having to replace freon and tighten the lines so we ended up with roof airs
Here are some pics of what I had setup -
Front inside unit - ran the lines right between the windows.
Here you can see the outside unit. We cut a hole in the bay floor to force the warm air out. System works best with lots of forced air into and out of the bay. Outside unit/CompressorTemps ran about 120 degrees with no forced air on a 90 degree humid day in FL. They ran about 97 degrees on an 86 degree day with forced air.
Here is the outdoor unit from the first one I installed. The manufacturer sent me a unit that never worked from the get go. After doing all of the work, this one came out and another one went in.
Here is another pic of the first system inside evap unit installed
Here is a pic of the lines running down the wall behind the fridge.
I'm sure there are more pics running around somewhere.
If I do another build - I'm not sure I'd try a mini split again. I really loved them for function but just not sure they are made to last 5 years on the road. They work amazingly when they do work. It was just a lot of money and time to have them fall apart. I put rubber isolators under the footing. Set down tightly on a rubber pad, left loops in my lines to absorb the vibrations, made sure the lines were fastened on tightly. Again - It didn't last 2 months on the road. If you part time, rarely move or have some AC tools and skills you'll probably get a little more mileage out of them.
I don't think anyone on this board has Mini-Splits and has put 5k miles on their bus.
We ended up with roof airs which are loud, don't have all the cool features and digital temp sets and displays and don't dehumidify. But they work, were cheaper and easier to install and can be easily replaced.
Good luck. Make sure you wrap your line good! Please let us know how it turns out when you are finished with the project!
