I had thought that a good weight distributing hitch (such as Hensley or Propride) would take care of leveling the pickup. Since my hitch weight for the 25' FC (including one of the above hitches) will be around 1,050-1080 lbs., should I take his advice, or will the Tundra (with Hensley or Propride hitch) suspension be enough?
To put it simply, a good weight distribution hitch should level your TV and move the proper amount of weight to the front axle. A rear air bag system will raise up the rear of the truck, but will not address the much more important weight distribution issue. It may look fine, but in fact be too light in the front. Steering and braking will be adversely affected.
Get a weight distribution hitch properly configured for you trailer and TV. Do not get the air bags unless you will be carrying heavy loads in the bed of truck when not towing a trailer. That is what air bags are for. Air bags are useful when towing 5th wheel trailers.
