Don't believe any numbers you read about Mobile or Elite suites!!! There are too many options that greatly effect the"DRY" weight of either. I have many Elite options like Quartz tops and millwork package along with extra cabinets plus a 6500LP Gen. Our 39TKSB3 weighs about 23K and has about 5,500# pin. I don't even have a fiberglass roof. Our last MS was a 36SB3 that ended up weighing almost 20K we pulled with a 11 HO Dually the pin was at least 4,500# I think it was more. People add WAY more weight to these already HEAVY RV's than they think over time.
We just traveled from Desert Hot Springs, CA to Ehrenburg, AZ yesterday with very strong winds. I did not even consider waiting until the wind died down because the truck and RV are VERY stable in adverse conditions. Now I sure can't say the same for many of the other RVer's that were all over the place crossing lines on both sides.
I have seen a few who think it's fine to tow such heavy RV's with SRW 2500's and 3500's but it's NOT safe. I guarantee they are over the weight rating of the rear tires. Even with 19.5's I still would not consider a SRW.
You just don't know when someone will pull in front of you or get hit with a big gust of wind.
After owning two Dually's I would buy this same truck again with a couple minor changes but the truck is extremely solid and the factory rear air ride works great at keeping the truck at the proper towing height.
