Oh thanks a lot guys; this is guaranteed to jinx my luck on the two old trucks. Now I have to get under the trucks and have a look see. Had lots of brake line problems on the GMC last year, better check it out before it gets too cold outside!
I took the bed off the GMC a few years ago, and had a ladder going from the garage flat roof to the crook of the oak tree 10' away. I lifted the bed up with my old Sears comealong and some rope

That was when I put in a new gas tank. I brushed it out pretty good with Rustoleum rusty metal primer, seems to be holding out OK. It all can rust out pronto. I'd like to get a cheap needle-scaler might make things easier.
The old 93 Ranger has been so reliable I've ignored the maintenance like a yuppie
Last time I used AAA was when my truck quit in the front area of Home Depot, with a new washing machine for the church house in the back. ( The Admiral washer was bad out of the box, but somebody else handled that...) A couple tough guys teased me by saying "You always haul merchandise that way?" The driver was totally cool, I tipped him when he said his wife was deployed overseas in the service. I got no problem with them, but I stay pretty local these days.
