My easiest location is underneath the trailer on the frame. This is for a Trimetric meter.
My last two folding campers I mounted the shunt inside (it was a Link 10).
Road salt is not much of a problem here. My negative lead was grounded by the factory not far from the battery so that's why I say easy location. Before I started this project I thought they had frame grounded it right below the converter panel. That was until I crawled under the camper.
I have used some #4 GAUGE FUSE HOLDERs from DAN-MARC that had snap on covers on them and mounted those under the trailer to the frame. I don't know if they have the COVERED METER SHUNTS or not... One of these fuse holders has been installed over a year now and all the connections and the fuse link looks good as new.
I am currently working on installing a battery current measuring digital meter project and ended up with the shuntless type DC current sensor where the #4 gauge cable goes thru a DONUT type sensor.
My setup is for a 75 DC AMP DIGITAL METER. This sensor is well molded and sealed etc. and should do well under the trailer. Bolts directly to the frame and you just route your BATTERY cable you want to measure thru the unit (no connection). I mounted two DC DIGITAL VOLTMETERS and one DC CURRENT DIGITAL METER in a panel near the door of my POPUP and will run 2-conductor cables back towards the batteries to grab my two battery banks and the main battery cable sensor going to my converter.
It all works great on the test bench so all I got left to do now is finish the installation on my POPUP. Nothing more exciting then to sit in your POPUP and watch your BATTERY drain while camping in the woods haha..

CAVER - My CONVERTER is FRAME GROUNDED just underneath the floor where the CONVERTER is mounted using a LARGE COPPER WIRE bolted directly to the frame. there is only ONE #4 GAUGE RED CABLE going from the CONVERTER CHASSIS to the BATTERY SWITCH up front. All of my batteries are direct grounded to the FRAME up front.
