Since I do the this with fire equipment for a living here's my advice, INSPECT if you can the trucks before bidding, at the very least call the POC (listed as the property custodian) and ask lots of questions, a lot of the stuff I turn in for disposal is just obsolete, getting parts to keep it in service is too time consuming or costly, for the fire departments or the forestry departments, a lot of it runs when we park it, that by no means assures that it runs when you come to get it (assume it wont). A lot of the stuff was run hard and put away wet, most was maintained well by the fire departments while in service (hey if it don't run ya can't put out fires) Stick to the timelines in the contract between you and GSA, don't even consider a default! it will cost you IIRC $200.00 OR 10% whichever is greater, if there are problems with pickup contact the POC and let them know most will work with you to get the stuff gone within reason. You will receive an SF 97 automatically FREE! for a vehicle and don't have to do the EUC thing. I will say every state forestry does things differently so your mileage may differ!
