Not calling you out. Just saying I do it and it's all within specs. Current F350 SRW's have about 3k of payload by the scale and Rams have 3500. You mention a lot of additional gear too which you might need to bring but the op could do without or place in his trailer storage to reduce weight on the truck. You also mention having a large family in the tv but the op is looking at what I would call a retirement floor plan that is a two person luxury trailer. I'm guessing it's a him and her situation in the truck. I do agree with you the a DRW gives more flexibility on loading etc. though.
