We recently got one of the VIAIR 88P Portable Air Compressors based on recommendations in these forums. Already, it has proved itself. On our recent outing my TV developed a leak in the right rear tire (I'm taking it in for repair today), and lost 20 PSI overnight. The VIAIR 88P pumped the tire back to 44 PSI within minutes. It's compact and ridiculously easy to use. Needless to say, it's going to be in the TV from now on. It came with a 16 foot air hose, but we also bought two more 6 foot hose extensions so we can use it on both the TV and TT tires.
