Gentlemen,

What is your preferred method of airing up after a day on the trial?

I was looking at this: http://www.amazon.com/Viair-40043-VI.../dp/B000X9AXR8

But it seems a little pricey.

I took the kids out last weekend to Indian Valley Reservoir and did not air down as I had no way to air up again. The kids got a little tired of the washboard type roads. Was I driving too slow?

Thanks for your opinions,

Clem
