I just use one of my scuba tanks and an old regulator, which I connected a 25' piece of that yellow air compressor coiled cord to with an inflator/gaug I got from Walmart. Not as professional looking as the Power tank kits, but it does the job, is cheaper and uses a bigger tank.
If you don't have a c-card you can get the tank filled with CO2 at a welding supply place.
I use the 3rd row seat attachments and a ratchet strap to hold it down in the trunk. When I'm not wheelin' I take it out.
A lot of people use PowerTanks and they seem to work well, I'm just too cheap to buy one, when I have everything I need already. </div></BLOCKQUOTE>
If I get a tank and fill my tires with Helium will my truck be lighter and float accross the water?

Seriously, thanks for the idea. I am going to try and find all this stuff and do it.
One last Q: How many tires will one tank get you? 37's? And it it costly to get CO2?
