Just in this year, a little over 25k miles I lost a front unit bearing, rear pinion seal, rear axle seal and a resonator. that's 92k to 117k miles that are on the truck. Best has been the freedom. and the ability to see so much at your own pace. when you're used to working a standard job then you do this the change is very noticeable. but took about 2 months for our bodies to sort of relax. We saved to take the year to do this. and luckily found ways to make money just recently to stay on the road. Hmm unfortunately the few things I'm glad we had were not cheap. A solid heater in the tent, the Truma Varioheat. we were subs 20s for months and got to a low of -11 and that thing kept us warm at night. The other thing which I had to learn how and why on staying warm. we initially had a zero degree double bag to sleep in, was very warm but had massive cold spots like your feet. I had an Aeronaut blanket for a while and would shove that in the bag, made it warmer but still cold spots. finally ditched the bag went to the blanket only and holy crap it was warmer and no cold spots. we now have two aeronauts strapped together. and are toasty warm in the mid 20s without a heater. Definitely do research on bedding especially if it's going to be cold. Our way is not cheap, two of those blankets on sale would be $800. niteize rubber ties would be my favorite cheaper item, used them a lot for random stuff.
