I definately wouldn’t take my open trailer to the motel. Leave it at the track with friends near by.
Nothing pain at all about restaurants and motels. No messes to clean up, no muss, no fuss.
Regards tools, spares, etc, my crew cab truck has plenty of room to carry what I need to race with. If I need a part at the track, I can run into town and grab it.
Anything serious that gets broke 99% of the time it’s gonna stay broke till I get home, unless it’s an easy quick fix.
Only two things I have broken in recent years was a trans and a rearend, no matter what I used to get to the track I wouldn’t have spares for those.
And stuff like a starter or a rocker arm I have plenty of room for, if I chose to keep spares of them.
I do need to invest in a portable generator for if my golf cart needs charged or the car battery, that’s on an off season to do list already.
The generator I can keep locked in the back seat of the truck if not in use.
All this said, at the end of the day, it’s personal preference. I just do what I do because it works for me, having had the experience of having done it both ways, plus the majority of my racing is done 30 minutes from home typically
