Joe, many folks I know around here have been driving their bolts for a long time and put many many miles on them....yet, when we talk about a Road Trip they all get awful quite. I just ask them why their truck will run thousands of miles stopping and starting around here but can't make a 300 mile run. The fact is they're just plain scared or have no confidence in there work.
I don't get to chance to drive on many excursions but I'm with Cletis, drive them. I just got back from a 300 mile round trip in the modified 37 that I practically did everything on myself.
Drive it with confidence and the more you drive it the more you'll enjoy it. I'm with the rest of the gang. GO FOR IT.
