I'm sorry but I have to ask, what happened with your trailer that you needed a multi-meter?
I'm using it all the time, from checking AA and 9vdc batteries to checking the house batteries charge. My meter also has a proximity tester that allows me to check if power is present at a switch, outlet or lite without making contact when I'm working on things. I guess some of us like tickling wires and knowing how thing work and some like to leave it to experts...

First weekend off the grid we had an issue with our fridge. We used a multi-meter to check fuses, confirm voltage, and generally troubleshoot. With information on this site, we determined that our use of power was too aggressive and the battery was low.
a bit of patience will need to be packed...... a bit for everyone.... don't forget a good dose of relaxation!!! After packing all the necessities ...... you will need that relaxation last but not least.... have a safe trip and a great time!!!!
I’m an old tent camper and my philosophy was/is, pack light and take only what you really need. I still feel that way, although if you look in my basement storage area you might not believe I still follow that philosophy. I do have to admit that my needs seem to have expanded greatly since getting into RVing. I just wanted to be sure that I wasn’t missing something and really needed to add a multi-meter to my basic toolbox.
