, to answer your original question, I would base my decision on actual weights not GVWR. Your preferred Toad is close to maxing the 5k hitch load in any event so I would carefully inspect the hitch, welds, and attachment fasteners and make any needed updates.
Frankly I'm embarrassed by the attitude and replies that some members have greeted you with. While I agree that the correct info is necessary to provide accurate answers to a question, at no point did I think you intentionally mis-represented either yourself or your equipment. In fact you listed each component on your coach and a simple Google of the model number, 372DS,
reveals a Coachman product. Since you weren't trying to sell the Coach or join the Elite Country Coach fellowship I assumed you had made a honest mistake or were unaware of the details and simply looking for some input to your question.
There are some very good folks on here with valuable information and I hope you give us all another chance. Most importantly, thank you for your service!
