The EUC is end user certificate saying you are a US citizen and using hte trailer for personal use and will not sell to a foreign national or country since it is prior military equipment. Expect those auctions min. bids to reach 400-900 on the trailers. At the time i bought mine I was watching them at Barstow and Nellis(Las Vegas). I got mine from Nellis because the ones at Barstow went for 200-300 more than Nellis. Also some of the trailers require an EUC while others do not. Try to find one that doesnt and it will speed up the process.
