I guess, the question that I have is, what's your main plan for the whole rig. My TC that I had was 41' and I had a 31' stacker to haul toys to the dunes, or to and from Texas, from Phoenix. 95% of our use was dry camping. So total length wasn't a major factor. Whenever we were staying at a campground, we didn't have to worry about the TC, because it was no different than a Class A. If you're looking to stay at campgrounds with the whole rig,...the wheelbase on both your TC and 5th wheel is what's gonna be the limiting factor. I'm pretty sure you've already thought about that. If you're ever passing through Phoenix and need somewhere to stop, you're more than welcome. I got enough room to park 5 rigs just in my driveway alone. Whatever you do, keep us informed,...I'd like to know how it all works out for you.
