I just bought a 5th wheel. I have yet to take possession of it:), I notice the tires are serviced with Nitrogen. So how do I maintain nitrogen filled tires?
I race karts, and some of the top competitors use nitrogen or dry air to maintain tire pressures over a race distance, but most of us just use regular air.. I see the reason, but I'm not consistent enough to be affected by the difference of a pound of pressure change.
I can't imagine that it would make much of a difference in the 'handling' of a trailer. :)
