Something to really consider is overnight staying at hotels/motels and thieves
The other thing is weather conditions
I went to Button Willow for a practice day yesterday with my shifter kart, I thought it was very simple to just throw it on the back of my truck and just go ( since it wasn’t even a race day )
As soon as I got there it started raining hard, like pouring cats and dogs
My beautiful clean kart turned into a soaken wet madness
So I had to work a lot harder to take it back to the shop, dry it out, and making sure every nut and bolt, fasteners, chrome pieces were free of water, then sprayed the whole thing with WD40, and wiped it down with a towel.
All that could have been avoided if I had taken an enclosed trailer to the track
