Starting reseach on Super-C, Thoughts? Opinions?

I enjoyed reading the thread on 6 months of research on Class C Rv's. But since I think my questions may be more specific to my needs or wants and not wanting to derail his thread here goes my questions. Here are my needs or wants. I don't think I really need a Class A Diesel. Plus I wonder about some of the towing capacity of these. We drag race as a family both kids and adults. I tow a 28ft enclosed trailer with the race car, parts, etc. Total weight of the trailer & contents around 7000lbs or so. I am currently zeroing in on two models the Jayco Seneca FS and the Thor Chateau 25SB. Because we have kids etc racing, we like the bunkhouse models. Now if money was no object, I think my choice would be made as I would choose the Jayco as it seems more heavy duty. But being a Ford guy at heart the Thor model interests me for a few reasons. No 1 the cost difference, No 2 like I said I am Ford guy(except for the dragster it's a Chevy engine, numerous reasons :) ). I believe the Powerstroke 6.7 to be a good engine platform. No 3 towing differentials. If you look at the links below the difference in the GVWR & GCWR looks to be significantly more. So in my simple mind that means I can tow a heavier load. I presume what I give up would be not being able to carry as heavy a load in the RV itself? Our usage of the RV would be maybe 2 times monthly on average, mostly fairly local 100-200 radius per trip. Maybe an occasionaly longer trip of a 500-800 mile radius. I have seen the Jayco in person, very impressive. I plan on going see both to compare this weekend at a local RV show. I have read some not so glowing reports on the Thor, but I think this is fairly new model I wonder if some of those are bugs being worked out. I would suspect to see a quality of materials difference between the two, maybe I will know for sure after inspecting both this weekend. Any thoughts? Opinions? Comments would be appreciated.
