We were in sort of a post nuclear homebrew. Technology and mutant monster type things.
We found this winnebago, took it into the nearest oasis and had it outfitted with some guns and other adventuring things.
This Vulture/Dragon thing has been raiding local towns, caravans, and an occasional oasis. We decide to put a stop to it. We camp out in the winne(which we have named the bull). So we are camped out in the Bull about ten miles outside the dragons lair, apparently it is out hunting so we decide to wait for it to come back, thinking it will be tired and less potent. In the middle of the night we are awoken to the Bull rolling allong the sands.
We look out the window and see two huge gigantic centaurs pulling the Bull with some rope. Eventually we sever one and light the other one on fire. We haul some Booty, they chase us. It lasted a good half of the session but remains to this day one of my all time favorite adventures.
