We did just what you are thinking about. Towed 1 summer with an 08' f150 screw. It towed our 7700# trailer "fine". Our little family grew (2 young girls now) and I realized that once I loaded the family, genset, and all our stuff I was overloaded. Last summer towing with our f250 I found out how much stress I was putting myself through towing with a 1/2 ton...instead of leaving heavy stuff at home, looking for fresh water at our destinations, constantly checking mirrors for sway, cringing whenever a semi passed, judging stopping distance, speeding up for hills, leaving early before the wind picked up etc I now just load and go, set the cruise and look for the next gas station. Sooo much more enjoyable travelling now.
