Nice one Tom!
Well, I have been where you are!
Flew in to get mine too, so the amount things I could was limited.
I packed in a sleeping bag and pillow, and few clothes to suit the April weather in KS. Phone and chargers, GPS, my AAA RV card, my Laptop, loaded with every manual and bit of info I could find.
What tools I could bring was a weight issue. I brought general tools like Flashlight, Vice Grips, tape, Leatherman, electrical tester, crimper, connectors, DMM, and Zip Ties.
Flight in and inspection went as planned.
I went to the local Sears and picked up one of these..
255 Pc Mechanics Tool Set: Never Again Borrow a Tool!
The plan was that it would be my "Onboard Kit", and it still is.
I also grabbed fuses, a hammer, big adjustable wrench, and a few other sundaries.
My drive home was about 1600 miles, and the beast gave me no issues beyond a water leak from the water heater and a blown fuse.
The good news is that with the drivetrain we have, you can get almost anything anywhere!
Enjoy the drive and keep us informed!
