Not the typical Gas vs Diesel, ½ ton vs HD question

If your fishtail was due to not enough tongue weight, then even a class 8 ain't gonna fix your problem. In that case the only fix is more tongue weight.

That was my first thought...too much weight in the back and the hitch gets light. That would be my first check.

Of course, 11.5k is 3/4 ton territory in my mind but that won't solve a light hitch weight problem. If you are planning to 5th wheel, it might be worth it to bite the bullet now.
