Don't forget to bring your personality & don't be afraid to walk up to a stranger & ask for help.
Many carry bulky ladders around. I don't but on the occasion when I have needed to reach the unreachable light bulb by the door or have been in a CG that allows maintenance such as waxing, I have always been able to rustle up a ladder from somebody. I do carry a fairly extensive collection of tools & have been able to pass the favour along to others with the loan of a tool or, when the RVer is tool operationally challenged, supplied tool with operator.
What goes around comes around.
