I'm installing an Orion TR Smart charger in a Mercedes sprinter build and I am wondering if there is a recommended placement for the charger. The manual does not say whether the charger should be kept closer to the input or output batteries but I am curious if it is recommended to keep the wire run shorter on the output side than the input side, which would require me to mount it near the house batteries at the wheel well in the rear.
Mounting it under the hood would however make it easier to run the wiring for the on/off switch which will be mounted in the dash. Any recommendations?
