Hey Bingo… I ordered the 10-wheel SAF-TTE TPMS on 28 Jan 2008 from
www.truckerspartstore.com at a base price of $489.00 plus $17.35 S/H for a total of $506.30. I checked their Website the very next day and noticed that the same system went on sale. I called them right away and found they had already honored the lower price and had turned in a credit to my VISA for $90.70, resulting in a delivered-to-my-door total cost of $415.60. I checked their Website again today and it looks like the 10-wheel unit is going for $439.00 + S/H. Maybe another opportunity will come along for even greater savings. Alas, the TPMS hasn’t yet arrived as of yesterday so I can’t comment on quality of workmanship or ease of installation. Happy campin’ Guy
