Welcome Tilly with your new toy.
I installed this spring, solar panel
kit Renogy 100 watts.
They delivered me the 100 watt panel, the length of wire # 10 required the panel to the controller (30 watts) and the required length of wire from the controller to the battery.
In their instructions they suggested intall one fuse 30 watts, between battery and controller, near the battery, which I did.
This way I can add two other panels 100 watts if necessary in the future.
I installed a mini meter reading for monitoring the battery voltage does not fall
below 11.9 volts. (I read that lower than that, damage the battery cells.)
4 roof supports for the panel are retained with VHB tape, protected against dirt, water and UV silicone with which I have no name in memory.
(For unbelievers VHB tape, my solar-panel is still in place and solid.)
I spent the wire by the vent of the bathroom, so no holes in the shell.
I used this spring until today and I am completely satisfied.
The trailer was removed the electric kettle, electric toaster, electric coffee maker ...
Everything is on a small propane
stove outside with necessary appliances.
All the lights
are replaced by LED.
With all these changes, it takes more time to live, taking the time to make our coffee, watch the cooking of roasted, etc ...
Have fun Tilly, adjust your system to your needs.
