I am not familiar with the Ragen but I have heard they are very well built (heavy) trailers.
The issue with toy haulers is that they are designed to be extremely tongue heavy so as to be able to support a balanced load while hauling toys behind the rear axles. If you think about it, starting with a perfectly balanced trailer and then adding 1500-2000 lbs of cargo on or behind the rear axles would leave a very unbalanced setup for towing. If you're not going to be hauling toys then maybe not a good choice to have a TH.
Even at 24 feet I would be willing to bet the tongue on that TH would be pushing 1200-1300lbs if not a little more and that would eat up the Tundra before you even attach it to the ball.
