Bought my 63 tr4 in 1969 soon after returning from RVN. Changed out the fluids and few weeks later loaded it up with camping gear and drove it from Missoula MT to the Oregon coast about 700 miles and spent several days driving and camping. While staying with friends in Portland the water pump began to leak. I removed the pump and took it to the BL dealer (on Burnside St. maybe?). I bought a repair kit and a mechanic at the dealership overhauled it. Simple times back then. Friendly dealerships and no need to make reservations for a campsite.
Several months later I made another extended trip with a gal I picked up at a football game; mostly fueled by sex and alcohol. Nope, don't think I'll say any more about that one.
The thing is I don't think I ever thought much about having a break down. Looking back though, the car was only 6 years old when I bought it. I still make trips in the car usually not as far but I do think more about having a problem, although it has never given me any reason to be concerned.
Hopefully if it breaks, we will be near a reasonably sized town with mechanic shop, a decent motel or B&B near a bar and a restaurant. While waiting for the parts to arrive maybe overnight, we will make the best of it.
