I will try and answer the many questions. On our 2350 we had another automotive seat installed in place of the barrel chair behind the passenger seat. Needed to safely carry our granddaughter. We found the corner bed to be a real pain. Maybe OK for young people, but not for us. Spoke to Stewart about the 2551. Needed more room to put another auto seat behind passenger. Therefore the evolution of the 2552S being a slideout with a couch. Found the 2350 dinette uncomfortable. Will be adding a short pair of legs to the couch table and wife will make a cushion so table can be used as a foot stool for relaxing. Stewart and Kermit came up with adding 12 inches to the coach which would give the extra room. By lengthening the coach they were able to add a slideout pantry between the refrig. and the couch and room for the auto seat behind the passenger seat. Some of the other items we had installed are: a Max fan 6200 in the bed area, it is a self contained unit that can be left open in bad weather as when open it has its own cover. Moved the Fantastic Fan forward to the slideout area. Had a 3 inch pullout drawer installed in one of the closets over the bed, room for wifes jewelry and computer. Wood rails on the tapered wing areas, which allows items to be left in those areas while driving. Two six volt batteries(More power available). Three way refrig. We always use DC when on the road, contrary to what some say there is plenty of DC available and the RV standard is not to use propane on the road(safety). Added insulation in the side cap area where there is none. Had an upgraded water pump, water pump strainer and flex lines added between the pump and the hard lines, eliminates the transfer of noise through the system. Had Ford Rep. come to the PC Factory and program the computer for the Keyless Remotes which gave us two remotes. We had shutoffs added inside the coach for the outside shower so once blown out they can be shut off and coach still useable in winter. On our 2552, PC has added an access panel under the mattress for the water pump and added a valve and hose so you can pump anti-freeze directly into the system, nice addition for those that use anti-freeze.
The 2350 on E-Bay is our old unit, if you can call nine months old. The paint is the Desert Sage and cherry cabinets, same on the new unit. Went with the Tom Tom system to eliminate hitting head on backup camera on the overhead and having to look up to see the screen.
Where can you find a manufacturer to do these custom items in this day. My hat is off to PC and I will promote their product.
