12ft or 15ft airline brake hose and why?

A picture would help. Do you slide your 5th wheel much? The Cascadia lines are ridiclously long and not well tended from the factory

 

I’ve got 12 ‘ for my deck lines

 

Get the 15’ coiled ones. I got the 12’ straight ones and it took some time to get them attached just right so I can make 90 degree turns either way. I had to buy extra spring holders to set it up with one long double spring and a short spring. So it doesn’t touch the catwalk.

Id get the 15’ coiled ones next time.

 

Add another tender. Biggest problem with long hoses is them getting caught on something low when you jacknife, then when you straighten up you tear them out

 

And always carry spare gladhand hoses and tools to Change them

and a box of spare grommets
