my first gen was running like crap and I ran out of gas left loon to springs back to loon on the slabs is where i ran out. i would take a 5 gal can just to make sure your good. Even if your good its nice to have in case of emergencies. My 89xj 4.0 ran the con loon to cad hill and I didnt have to fill up till tahoe. I would say it depends on how much time you spend with your motor running and waiting in line and if you have to keep it running to use air or a welder then you might want to bring extra.
hmmm memories......... i burned 1/2 tank in the stock tank of a 84 runner.
