If you're looking at big units, the Host, Chalet and Eagle Cap will be your focus. Chalet does a limited run each year that is not advertised if those units appeal to you. My observation is that Host has the best build quality of the three and Eagle Cap has slipped to third.
I suggest replacing the rear leaf pack with a heavier one from SDTruckSprings.com - If you need additional spring support later, it will be easy to add to StableLoads, air bags or Timbrens for final tuning. If your truck does not have a rear stabilizer bar, look at installing the heaviest ones offered by BigWig or Roadmaster.
