To touch on this point, just thinking through things can save you a lot of money. Being intentional about the mods you ACTUALLY need to meet a goal or improve things.
I'm in a fullsize Power Wagon, one of the most capable fullsize off-road trucks you can buy. And I constantly see guys running out with their new 2017's buying wheels so they can run 35's or 37's. Buying spacer lifts, etc. But 10 seconds of research would have revealed you can run those on your stock wheels with no lift. Or just randomly replacing suspension components because ..... it's better somehow... ???
Being really intentional about my build and testing the limits of my truck in stock trim first before doing mods, has saved me a lot of money.
There seems to be a rush of first mods people do on any platform. And sometimes, I'd argue a lot of it is a pointless waste if you don't even know what your goals are. Or what challenges you'll encounter when you're out overlanding.
What kind of clearance are you getting with your Power Wagon?
