In the Elkhart, IN area, I was VERY happy with the work I had done at ProCustom Inc. The Dynamax OEM couch, dinette and Serta mattress looked great but, spend more than 20 minutes sitting or lying down and, you'd find it to be quite uncomfortable. I met Jack Harris of ProCustom, (574) 350-8989 at the FROG Rally last year. I was able to see their work and was impressed. My "king" mattress was changed for queen width foam type mattress (I can now use standard queen linens with only 4" of extra fabric at the foot of the bed) and, an Amish craftsman was brought in to measure for a custom sideboard, cabinets and dining table. A good recliner finished off the package. MUCH more comfortable than the OEM eye-candy.
NOTE: at ProCustom, you can sleep in your RV at night while it's being worked on during the day. You don't have to pay for a motel.
