I towed a 35'3" TT with my 2006 F-150 Crew Cab. Once the Equal-i-zer was tuned properly, I had no sway and the whole rig felt solid. It took quite a few trials to get that feeling but once there, sway was a non issue. My current rig is 32' (SV-291) and tows the same after a slight readjustment of the Equal-i-zer.
Would I like to have an F-250/F-350 ? sure, does the F-150 do the job safely ? Yes it does. Your 295 is as long as my old trailer and your 2010 F-150 with proper sway control and weight distribution should be able to handle it just fine. I am just not breaking any speed records and I am completely fine with it.
Get a decent sway control/weight distribution hitch and enjoy that fantastic trailer
