I purchased my A3800 from RecPro. Shipped the day after I ordered it. Did have a problem with FedEx delivering it due to the weight but that was not RecPro’s fault. The only problem I had with RecPro is I ordered the Non-Ducted model, when I received the unit it came in 2 boxes, one being the main unit and the second is the inside shroud. Being impatient I took my old unit off before unpacking the new unit. The inside parts box had the correct pieces, but then I noted on the box that the main unit came in said Ducted, of course it was Saturday afternoon and I now had an open hole in the roof of my RV. Went in and researched it and noted that the only difference appeared to be the plenum needed between the unit and inside shroud. I installed the unit and built my own plenum using foil lined fiberglass board. It fits perfectly in the existing opening. I was fortunate to have a pole barn where I used a block and tackle to pull the old one off, then drove the rv out, lowered that unit down then. Hoisted up new unit and then drove the RV back under the new unit, then lowered it into place. The unit has the new gasket installed, so on top just caulked it while lowering it down, and other than putting the outside cover on you are done outside. Inside you put this frame in place, then attach with 4 long bolts, since you don’t need any of the existing control wiring I just covered with electrical tape and tucked it out of way then hooked up the 110v wiring. Installed the plenum I made, then the inside shroud snaps in place and then installed screws and that’s it. Another advantage to this unit is I am 6’ 2” tall and kept hitting my head on the Dometic Shroud, the one on the Hamilton is not as thick and I no longer hit my head on it. The outside unit is taller but I have installed vent covers on all my vents and I don’t think this unit is any taller than those. Before installing I was not hooked into any electrical so no 110 voltage to worry about and I pulled the 12v fuse feeding the unit. This unit is operated by a remote so the existing wall thermostat will no longer work. I have not installed it yet but I purchased just an inexpensive thermostat for the furnace only. One of the questions was how hard to remove the Domtic, and the answer is not hard at all. Removed outside cover (4 screws), then the inside shroud unhooked the wiring by just cutting it, then there were 3 bolts holding it down, removed those and the unit came right off.
