TexasPride.. You can go with whatever "tow rating" numbers you wish to use..
This includes the truck and trailer.
Based on my past experience with both, I've found the trucks ratings do not mean a fully loaded travel trailer, and the trailer 'dry' weight ratings do not come close to what you take off the lot before you even put your first item in the trailer..
Anyway, all we are telling you is what our past experience has taught us.. (I assume that's why you asked us in the first place??)
If you have never experienced the "printed" numbers to the "real world numbers", than now is your chance.. :)
Been towing things since I was 16 years old and that was back in 1979..
Good luck with whatever you do.
