The 34H sounds similar.
I have 4ea. 100w panels on the roof that feed into a J-Box next to the fridge vent. I drilled a diagonal hole from the box to the rear fridge cavity and dropped straight down to the charge controller located under the fridge. From there I have a piece of plastic conduit to the battery compartment that contains the batt temp sensor, ext. voltage sense, and engine charge leads (5a trickle). Along side the conduit are 2 pieces of 4ga welding cable covered in Slit-Wrap.
I'm sure some will complain about the run to the batteries, but that's one of the reasons I have 21v panels, ext. voltage sense, and the 4ga feeders. I see charge currents in excess of 30A at the batteries.
