Thanks, again, everybody. One thing I may not have mentioned is that my Tundra doesn't have the leaf springs (just shocks in the rear) so my first choice, the StableLoads, is not an option.
This is my big winter project so I have a few months to decide but, right now, I'm leaning towards the whole kit since those who have it constantly say they are "awesome" But I'm bringing the Tundra in for an oil change to the dealer in a week or so and I'll check in with their parts department to see what kinds of options they offer. (I purchased the bed cover from my dealer that's four very sturdy panels that are easy to lift up and are also removable which is awesome!! It's also almost completely water/snow proof.)
