7 yrs FT travel and I carried NO Spares.
Easy to get almost any part overnighted IF ----IF needed
Tools ....carried a basic tool set
If needed could buy
Although we traveled back- roads/secondary roads it wasn't like when I use to go rock crawling/deep canyon off-roading. Then I carried lots of spare parts cause I was way out in boonies where only off roaders could get to.
Basic tool set
Assorted fuses Mini and Large....Auto and glass
Voltmeter, tire gauge, infrared temp gun
good jack
torque wrench
socket set..specially tire lug nuts
Credit Card/Debt Card
Sometimes less is more.......if I hadn't used/needed in 6 mos. didn't carry it
