I have been researching buying my first  Pre-owned Motorhome and the brand looks like going to be Newell. with the help of this Forum I have narrowed down the year because of some improvements. Steerable tag started in 2004 with these 3 coach #671-681,685, this is an option looks nice to have. 2004 and newer gives you Valid Slides and Spyder multiplex single wire. The only question I not sure on is in 2004 Newell used Detroit Series 60 engines "500HP", a few C12 and C13 Caterpillar then in used the C15 Caterpillar for the next 4 years. I have driving a few Diesel trucks but not enough to know about the engines. Is the Detroit 60 an ok engine power wise for this Couch or is it better to look for a Newell with the high C15 Cat with 625 HP..
thanks
