Tow vehicle help

I’ve started the search for a new tow vehicle and would like some opinions. It will be a diesel of some sort but that’s about where my decisions have come to a stop.

All I tow is our boat, which is a 2018 SAN 210. That said, I do tow it a lot. Our lake house is a 3 hour round trip which we do weekly in the summer and at least one 5+ hour trip each summer to a new spot. We live in Texas so the Lakehouse trip is relatively flat. I’ve looked at both half ton diesel options, the Dodge eco-diesel and the Titan XD diesel. Of course the 3/4 ton options are all of interest but the budget starts to get stretched with these. I want to stay under $50k. I can get a new Ram2500 for that but no where close in the Ford and until Chevy decides to put rear air back in their trucks I won’t buy one.

Interior options are critical as we will drive this vehicle a lot. So, do I do a loaded 1/2 ton diesel brand new or a used 3/4 ton and roll the dice on used?

Any goods/bads/uglies to be aware of? Will the 1/2 ton ride a lot better with no load? Any help would be appreciated.
