Thank you all for the feedback. It is much appreciated. Coming from 2 travel trailers, I am very tuned in to the weight issues. When I pulled with a 1/2 ton, it almost became an obsession to make sure I was well within my limits. Then having a 3/4 ton diesel made that much easier but then it was about balancing the loads :)
I did a bunch of looking around last night and the only units that had more than 5000 lb towing capacities were a couple of class C's made by coachman and then Thor. And even then, they were only 7500 lbs. Then I get curious as to how they are getting 7500 lbs when almost all others have 5000. AND, I'm assuming that is with a 150 lb person driving with no gear, 1/4 tank of gas, etc...
One style of unit I found intriguing was a Super C on a Ford F550 chassis with a diesel engine. I believe this was made by Thor as well. I haven't had the chance to dig into build quality on those units but it is something else to consider.
Looking for that "perfect" unit is really a fun process. I appreciate the feedback you provided.
