I am happy with my 08 Tourmaster. Length is listed at 42'9". It only has a Cummins 360 and it only has 1 axle in the back. To me, it has plenty of power and it does not porpoise. But I have not driven bigger engines or tag axles before so I can't compare. In terms of customer service, my own experience is that they are terrible as you mentioned. I called them multiple times, auto-message directs me to a regional manager, which directs me to an answering machine, but I never get a return call. Luckily Freightliner and Coach-Net and the people on here and rv.net have been most helpful enough so far
