I do not always do what I say but the lighter trailer will have more of a safety factor for you . At one time they said to stay 15% under capacity of the truck trailer tow cap.
You will be really close or over on your payload capacity on the heaver trailer. I personally would take your empty truck to the scales & weigh empty (but as close to ready to camp as you can) loaded. You might be surprised. For us two adults, the dogs, a full tank of fuel, hitch, and stuff in the truck (cooler, DW's pocket book,
, grill etc.) puts us close to or over 1000 lbs. of cargo.
Good luck......... I would not worry too much about a 2014 though, as our dealer always has 2-4 year old new trailers on their lot...... If had the $ when we bought our current trailer the dealer had a 2010 Sabre on the lot that had sat there since new that we could have bought at their cost.......
