Along these lines I will comment on what I carry.. This starts with a cut and paste of your list.
Electrical Spares/Tool Kit
Awning Repair Tape..... LifeSafe..... RE3848
I carry assorted tapes. Masking, Duct, Gorolla, Electrical and "Rescue" (Silicon tape)
Fuse Circuit Tester..... HF..... 67724 I use my meters or test lamp
Fuse Puller/Tester..... Bussmann..... FT-3 Common needle nose pliars on my multi tool
Assorted fuses: The big assortment from an auto parts store
Hose Washers Yes.
Kwik Klips 1/2" Not sure what these are
Lamp..... Sylvania..... 1156 LL You might want to go with 1141 till you get everything changed over to LED.. 1141 runs cooler draws less power and does not melt the socket like 1151 can. And I do not carry colored lamps. Just clear.
Lamp..... Sylvania..... 1157 LL I do not use that lamp anywhere in the RV
Multimeter..... HF..... 98025 Several, I am an electronics hobbiest That happens to be 2 of them.
Trailer Light Tester..... HF..... 66526 That too Though It is not an HF and I do not know the part number.
2 small Flashlights Several.. Assorted size up to a 5 Cell "Mag Light" like the cops carry.
I also use a 12 volt test lamp, again I have several, the store bought one looks like an ice pic with a more or less clear plastic handle and a wire sticking out.. I have had TWO 12 volt failures recently where this device was very useful in tracking the problem, but a VOLTmeter said there was no problem. And yes, I know why.. But the test light has 3 indications.. ON/DIM/OFF and you need not even look at it in most cases so it is very useful.
The reason I have several is sometimes it's easier to grab a wedge type Dash Indicator lamp and attach wires to it.. The rest are made that way.
I also keep an assortment of spare device batteries.
Home was where I park it. but alas the.
