I'd love to hear how that extension works out as we have the 37lx (16) as well. We replaced mattress with a memory foam and bought 2 red leather footstool cubes for the sofa. Also, installed new, longer, faucets for the bathroom sinks as they were too short. Also, a metal clip to keep the refrigerator closed. Didn't like the cheap strap.
Not really a mod, but we installed a Splendide washer and dryer. Love it. Also, ordered custom dash cover since our dogs like to jump up and look out the huge window. Fits perfect and looks great.
You are right, it doesn't require much as we love the floor plan and functionality. The smoothe ride is amazing (compared to our Class C) and love that huge windshield. Oh, adding 2 more batteries next week.
