They don't even look at your GCVW, if you arent over on your axle ratings, tire ratings and 26,000lbs your good to go. Do a search on weight ratings there is plenty of discussion on this topic.
The DOT does not regulate non-commercial vehicle operation. The states each have there own written, and in some cases unwritten laws pertaining to recreational vehicles.
First, there are many Class A motorhomes which exceed 26,000 lbs by a considerable margin. Although many states have laws requiring some version of upgraded license it often is not a CDL since by defination a CDL is required only for commercial trucking. However, most states which have these laws have chosen not enforce these laws for recreational vehicles. These reason is two fold. First, there has not been a significant safety issue with RV'ers, and secondly, they have no desire to chase away tourism.
As far as towing is concerned there are a great many HD 3/4 ton trucks out there pulling very large fifth wheels. In fact, for a time it was quite popular to use Dodge CTD's as hot shot commercial truckers hauling VERY large loads. Ultimately, the government cracked down on these grossly overweight trucks, but it was proven that the Dodge CTD can handle a very large load. Before I knew better, I hauled an 11. 5' Lance camper, water, three kids, mama, and our St. Bernard camping. Often, I would have my 22' boat in tow. Looking back, I was probably way over my GVWR, GAWR, and tire rating. Luckily, I never had a problem.
The Dodge can and will handle a load far greater than it's rating. However, you have to consider the fact that you are overweight and drive accordingly.
In my opinion, take the Gross Axle Ratings and Tire Ratings pretty much as gospel. Exceeding those can lead to some very bad things. I've spent many miles over my GVWR and GCVWR and not felt uncomfortable. However, I do drive cautiously.
Just my $. 02
