So I'm going on my first long road trip with the R from LA to San Francisco. I'm a bit concerned the beating it'll take in the summer heat and the long drive but I think it's time I took it on a road trip. I just had it serviced 3000 miles ago, but that was a year ago. The car's been mostly sitting in the garage for the better part of the year. Anyway, besides checking the obvious things like tire pressure, oil and coolant, what other things should I check for to prevent a disasterous break down in the middle of central CA?
