we have a Verizon Jetpack for WiFi, A TV if we have electric hookup, and carry one of those small garden knee pads for when I put the stabilizer jacks under the frame, beats kneeling in mud or on stones. Plus I carry tools and spare parts. Don't forget a hammer if you stake down an
awning or screen room. Bungees and wire ties can be handy, as can duct tape.
