Welcome to the family Mike.
When we received our shell model we ordered it with just the two connectors (no solar panel) so the wiring was not connected to the battery. You will find two sets of two wires (black and red) coiled and secured near the "Sure-Power" unit in the battery compartment.
As "Wandering" suggests go back to the seller. If they are the dealer they will help you. most of us use a solar controller permanently mounted as most of us eventually add a roof solar panel to run and charge the battery for a portable or front opening compressor fridge.
I'm not familiar with the Victron either. Contact them and see if they have an installer in your area. If not, get the install instructions and locate a mobile electronics shop which is what I did . They installed my Trimetric battery monitor for $75.00 (well worth the price because I have a professional install with no problems to date).
You don't say, so guessing you probably ordered the "tower" on the drivers side which contains: propane bottle on bottom. Battery compartment above. And either a stove or empty shelf on the top.
Portable panels with built in controller
I found these units to be very heavy (around 26-30 pounds) and expensive.($200 Renogy) We purchased a 60 watt stand alone panel (about 12 pounds and less than $90 )And a MorningStar charge controller
from Solar Blvd www.solarblvd.com.
We use an Engle top loading portable compressor fridge that draws only 1.5 amps average after the cool down period (20 minutes from 108* temp to 39*. 2,5 amps continues draw) and made up a 50 foot length of 12 gauge 2 conductor wiring for shade camping.
The 60 watt puts out 3.5 amps per hour which is enough for our needs.
For your application you may need a 100 watt panel. Consider a flexible as they only weigh 4-5 pounds and can be stored under your mattress when traveling. Yes there have been problems, however just from one manufacture that as of this writing refunded everyone's money and took the product off the market. Research Flexibles on Amazon plus there is a "pinned" post on flexibles.for your review. Click on the link.
In my build post I have a lot of info on my experiences with solar that might benefit you as you do your research and build your shell.
