I have to disagree with an F150 5.0 V8 w/ Tow pkg not being enough truck for the 24M Northwood Nash. Looking at their website and specs for 24M, it says dry weight is 4975 lbs, hitch wt is 475, and carrying capacity is 1535 lbs. GVWR is 7000 lbs. That truck can pull, safely, that trailer. We are at 7k loaded in our 30 foot trailer (not the quality of the Northwood I do admit) and our 1500 GMC does a fine job. Would a 3/4 ton truck be better? Sure.
By the way, i agree you need the GVWR of the truck to get the big picture...I'm just saying initially the 24M and the F150 should be a match.
Not trying to start a weight/towing war! Just my 2 cents.......
