I have found some good advice in SurvivalBlog over the years. For example your referenced GovLiquidation.com site some years back. Fort Polk, Louisiana is a two hour drive from my retreat. I bought a $10,000 MEP-002A 5 KW diesel generator with only three hours clocked on it at auction for $1,500. I was somewhat concerned that it might not work or have problems with it but I decided to chance it.
Picked it up, brought it home, hooked up two batteries and it cranked right up. Runs like a top. Amazing that the government is selling stuff for what it sells it for but it does. I have had it for nine months and run it every two weeks and have not had any problems with it.
About every six months they have a batch of about 20 or so generators up for auction. I will probably buy another. Can’t beat the price and the generators are built like a tank.
I also got a batch of 70 rolls of concertina wire for $400. They were in very good shape. These are the long rolls that sell for about $75 to $100 a piece, new. I stored them in the very back field at my “farm”. – Carl D.
