Victron Smartshunt install
I just got one and wondering where best place to put it. I know it is not waterproof and I am not sure where on the inside would be best to put it. I think the wires go to the back of my TT.

Okay, on the negative side of the battery, as close to the battery as possible. The battery box might be big enough to hold the shunt, if not, you can always buy a weather proof box with grommets and put it on the frame of the trailer, as close you the battery as possible.

Generally the shunt can be squeezed in the top of the battery box but it is more trouble and not as clean as using the waterproof box mentioned just above.
To put shunt in the box a flat copper bar needs to be made to mount shunt to negative post, the plastic battery box needs to have the lid joint sealed (one strip on the lid and second on the top of the box) with dense foam tape and the areas where the wires previously came out of the box blocked and sealed. The wires exiting the box fit between the two layers of foam. The vents on the lid need to be sealed. If all this is not done well box will leak. So a lot of work and potentially not sealed well.
You maybe adding more wires to the ground in the external box so make sure that you have more than enough space for wires.

Before I did my inverter install I used Velcro and attached the shunt to the side of one of my batteries in the battery box. The box is a Camco duel bat box and there was plenty of room on the side. Never had an issue with water or moisture for over a year of traveling.

There are exterior waterproof hobby boxes that could mount to the battery box. Then the shunt in it. That will be my plan when I install my shunt.

The shunt measures the current flowing through a wire. The amount of current at the battery post should be the same as the end of the cable. Where it is mounted should not really matter as long as all those little tiny electrons get measured. It should not matter how close to the battery it is mounted, as long as there are no additional wires where the electrons will bypass the shunt.

It needs to go on the main ground wire to the battery. There should be no other wire after the shunt. In other words, the next thing in line is the battery. If there is any other wire, it certainly could effect the actual flow of electrons counted.
