What size 5th wheel can I safely tow? 99 Dodge 2500 4wd Cummins diesel 5.9. I know stopping it is the biggest problem. Considered a pac brake but mechanic said it would be hard on engine? Any opinions...
Not quite right - trailer brakes stop the weight on the trailer wheels, truck brakes stop the weight of the truck. The right size fiver will not cause you to exceed any of the truck manufacturer ratings. Payload is the big one and a fiver pin weight will be more than you expect. Figure out whats left of your truck payload once you, the family and "stuff" are loaded. Do the math (and get a good brake controller!) Hint:- you will be limited to a VERY small fiver!
