Sorry for the delay... got hung up with something and was not using Internet.
Thanks for all the replies!
Based on feedback from people, here is what I am most likely to do.
1. 60a fuse on vehicle battery with 4 gauge cable running back to tailgate, or I will do like @NRALIFR did and come straight in by the front of the truck bed because I think I have an existing port near that spot on my Ram 2500. Although this looks harder to get to once camper is on the bed.
2. Tailgate 2-pin connector (as seen in photos by previous posters) to facilitate removable connection to camper.
3. Solved one of my main concerns about how to cleanly enter the camper to the battery compartment with this new cable run because I found a pre-existing port from the camper manufacturers that is not being used.
4. Connects to Victron Orion-Tr DC-DC Smart Charger at 30a capacity. This charger has ignition detection, so no on/off is required unless desired.
5. 60a fuse between DC/DC charger and camper battery.
That should do it!
@toddb - Converter is not involved
@kohldad - Thanks for the cable run advice!
@mike/kellie - I encourage you to look at the slightly more expensive Victron Orion-Tr DC-DC Smart Charger for the extra features, like ignition detection and Bluetooth monitoring.
