2-2.5 hours in the 182 for the 300 mile trip.
Me, for 1,500', I would be looking for a Bonanza or Comanche. 182 is a great plane for sure, but if you are traveling distance, speed is nice!! Getting the gear inside out of the slipstream pays dividends quickly.
Bonanza gear is TOUGH!
But if it is a 182 you want, give a few a try. the 180's sequentially fly like a sports car in the early years, to as described for later models- a big truck. Early ones suffer more wing flex cracking and gear rivet working, but fly lighter. New ones carry more, and have less rivet working due to extra braces/metal to support them.
Again, I would be looking for one in good condition with options I wanted- that would be my priority. All will achieve your goal.
