I just added my signature. You didn't miss it. I did not have it up. I have not received the exact specs on the new Momentum 385th but I should be getting them soon. I was told it was going to be about 2 feet longer than the Momentum 355th which is 39 feet 11 inches. From what I heard from my RV Dealer (Tom Schaeffers in PA) who is at the open house, the new floor plan is incredible. I saw the Momentum 355th at the Hershey RV show and absolutely loved it but I was than told about the new floor plan. That is what we decided to order. I looked at all the other toy haulers from Cyclone, Fuzion, Raptor, Voltage, Road Warrior, XLR, etc and I found the Grand Design Momentum to be far superior in construction and design compared to the others. Add in the way the Solitude has taken off at the dealerships and the quality of that unit and it was a no brainer to order the Momentum. As a side note while I was at the Hershey show I spent a couple of hours with Marc Hauser, General Manager of Grand Design. We spoke alot about the different lines that Grand Design has out and the direction the company plans to go in the future. I also was able to speak directly by phone with Bill Fenech and Don Clark, co-owners of Grand Design. They both could not have been more pleasant to speak with. They are taking their customers input and critique to make a better product to build for us. Don't forget it was these 3 gentlemen who started Keystone from the ground up and made it into what it is today before splitting off and starting Grand Design. If I was a betting man I would say Grand Design will be considered as the premier RV manufacturer in a very short time.
