I had a friend with a model helicopter, radio controlled. He measured his outings by what it cost to repair everything for the next outing! His mindset was:
a) it's fun
b) expense is part of the exercise
So, it seems that expectations help.
If you're getting uncommon expenses for repairs with over-the-road operation, well, I guess we all complain a bit.
If you're doing some serious off-road work, perhaps it's just a matter of adjusting expectations?
I wasn't too happy with needing to replace the EGR/FCV on our Libby so soon after buying it, without warranty... but, I've taken steps
and its run like a top with no problems since. I love it.
If it starts costing too much, I'll join you.
