Need help picking out a used truck to tow

If those are dry weights then you'll be in 3/4 ton territory once loaded up, mostly because of the tongue weight and low payloads of most 1/2t trucks. Keep it empty and travel with the family in another vehicle you might get away with a 1/2t but it won't be fun. Why limit yourself. Get the 3/4 and take what/whom you want with you.

In any case a WD hitch will be a must. Something with built in sway (Equil-i-zer or Reese dual cam etc) would suit best.
