First the new Hawk freshly mounted on the truck.
Very first simple mod, a digital thermostat with simple 2 wires and heater only.
Second mod, removing the AGM battery in the new Hawk and replacing with the 2 Battleborn Lithium batteries from the old Hawk, which have been working out nicely.
Also wired in a Victron 30 amp solar charger into the factory wires that go to the roof and back panel terminating in a SAE plug.
Interestingly in my owners Manuel two SAE plugs with stripped wires on the other end were included (greatly appreciated) so I just crimped those directly to my solar wiring which terminates into MC4 connections on the 2 175 watt solar panels I installed on the roof. (More on that later)
The two Renogy 175 Watt solar panels I added to the roof which weigh just under 20 lbs a piece. I attached them using 3M 4950 VHB tape and covered the Z-brackets with Permabond tape.
And lastly I added the excellent 712 Victron Battery Monitor to keep tabs on everything.
