Need more help with tow vehicle/truck trade/purchase!?

We are towing 6000lbs +/- with a 2013 f150 CC Eco. Tows just fine. 25' box / 28' overall.

Problem you may have ( depending on family size ) could be with payload unless you get max version. We do not have that version but there are only 2 of us. We travel pretty light but are still close to our max payload with us and 2 kayaks.
