What are you towing with your F150?

Few years ago I towed a 2008 Keystone outback 21RS with a 2006 F150 lariat 5.4, tow package, 3.73 etc. Honestly the 5.4 had plenty of power what I didn't like was the four speed. Went from that to the diesel 6.4, and now back to a gasser. Only reason I wanted the bigger truck was because I had the opportunity to drive them on my job. Otherwise the F150 did perfectly fine.

Think the GVWR of that trailer was in the 6200lb range.
