I do not drive with two feet.
The tongue weight on this trailer is 1380 lbs.
My question is when going down the road on a highway do I need trailer brakes at 6.5%.
That was answered by "old-biscuit" and the user manual he included so kindly.
Your 2012 Ram with Cummins Diesel has a ' Variable Geometry Turbo
)' meaning that vanes inside turbo open.close to provide engine braking.
It is an EXHAUST BRAKE vs an engine brake as it restricts exhaust flow thru turbo.
You stated you have a 14K 5th wheel but now state it has a pin weight of 1380#.
That MUST be a MFG. published 'DRY' weight based on DRY Trailer weight
I tow a 14K 5vr and WET pin (trailer loaded for camping trip) is 3000#
YOU NEED to load up truck and trailer fully (just like you would for camping trip) and then go to CAT Scales and get weighed
and then just truck (drop 5vr in parking lot)
Cost $10-12 with free reweigh
Weight tickets will give you trucks Front axle, Rear axle, Trailer axle, total weight.
With REAL weight numbers you can see how much over trucks GVWR you are (and you will be)
With REAL weight numbers you will see how much you are over PAYLOAD (indicated on tire data sticker on door jamb) (and you will be)
With REAL weight numbers you will see how close/over you are on trucks rear axle rating (you will be)
With REAL weight numbers you will see how close you are to trucks rear tire MAX Load Ratings (you will be)
Find your 2500 trim level in chart and see what YOUR trucks ratings are
Be better informed so YOU can make informed decisions
