These weight discussions are exhausting...being a newbie the issue of weight is very confusing. The manufacture tells you one thing to sell the truck. The RV dealer tells you another to sell the trailer. The only absolutes in this discussion seem to be 1) your tv has a weight limit developed with safety in mind. 2) your TT also has a weight limit so that it can be operated safely. 3) whether you, as the owner of both the tv and tt, choose to go inside or outside those limits is entirely up to you. For myself, having tried to tow my 6600 lbs TT with a 1/2 ton a few times, I decided I would be more comfortable stepping up to a 3/4 ton. I know I will be safely inside the parameters on both the tv and tt. Having that peace of mind with a wife and two small children riding along is worth it to me.
