We recently took delivery of a 2022 337RLS. Upon getting the coach home and parked in the garage I proceeded to "dig" inside to clean up sawdust, screws, wire tires, and other construction remnants. I pulled out every drawer to look behind it, checked inside every cabinet, looked under all the furniture, checked behind the tv and fireplace, everywhere I could possibly access. What did I find? One screw lying on the floor behind the fireplace. There was very little sawdust and no other debris inside the coach. The floor register in the bedroom was spotless and I couldn't believe how good the heat airflow was. Kudos to Grand Design for I expected to find much more here.
I then went to the basement and removed the panel to get at the heart of the coach. Here I was a little surprised at the way the wires were run with no apparent logic. There were wires run over and under the heating ducts and plumbing lines. There was a large loom of heavy wires crushing a heater duct. There was a single wire resting on the heat sink fins of the converter. Most wires were tied down and supported but some weren't. There was quite a bit of saw dust in this area. The mix of pex and vinyl plumbing hoses looks like a disaster waiting to happen. The coroplast had a gaping gap on the side of the frame where I could stick my hand in there. The coroplast was sagging pretty good and I noticed there were no drain holes for water from the road or leaks, to escape. I put some small 1/8 inch holes at the low points and when I was above the axles I got clear water pouring out. I'm not too concerned at this point because it wasn't much water, it was clear and the coach is winterized. I'm hoping it was sprayed in through the gap in the coroplast I mentioned above when the dealer washed the coach. In any event I don't want this area to hold moisture.
I was glad to see the wet bolts on the suspension. I checked for bad or loose crimps on the wiring and didn't find any. The roof and caulking looks good. Everything works correctly. All in all I feel we got a pretty good coach compared to others we have purchased. Especially considering the times we are in at the moment. There is no perfect rv but all in all I'm very happy with this coach.
