Well, let me be the first to complain about the CS. A little history. First MH 37' Georgetown gas. The chassis was fine and we went all over with it, Canada, Key West Yellowstone. Chassia great. Noise not bad. Georgetown part sucked. Cheap, cheap, cheap. 4 trips to factory for repairs lasting a week each. Thet paid all expenses, no reciepts asked for 2005. After a year and 30,000mi we traded up to DS, 39' diesel HUGE diff. Loveditt. After 8 years traded in on a CSgas 3953, 2013. Beautiful rv. We had the cream color that is avaible on the BS. The Ford chassis was great, ran great,noisy on grades. ,5 mpg towing. put 5000mi on it and had so0 much trouble with the Newmar part. Leaks everywhere. Slide out controller failure. BIRD charging system failure. Had to keep a charger on the chassis battery. Replaced parts etc, still failed. Had laminate wood floor that showed digs etc. and was deteriorating fast. . Was just getting fed up. Too many problems. pais 145000 abouts in 2013.
Looked around to get back in a DP and ened up with a nice used Tiffin Allegro Bus. Very happy now as this has al the bells and whistles Of course had to kick in more bucks. Rides great and cruise cntrol never slows down much on grades.
IMHO take what you want to pay for a new gas and put it on a used DP.
