Yes they pull better but how about stopping with all of that weight behind a 10k# truck??
Same way semis stop pulling 80,000 pounds.Trailer brakes and compression brakes. I pull and descend 10,000 foot passes with no problem. I very seldom touch the brakes except maybe for a swithback tight curve. Stopping quick is always challenge no matter how much you are hauling. I try real hard not to get into that situation.
