Hello from the great northwest
We recently bought our neighbor's 2016 pop-up A-frame trailer. It's kept me busy...
Truck: had to wire it up for the 7-pin connector (it only had 4-flat) and install a brake controller. This took a while. Pro tip: don't snip your brake light wire until you have a plan for how to tap in!
Trailer: replaced the power inlet (the cover was broken), and I'm in the process of replacing the water filter housing and replacing the (original) tires (and greasing the wheel bearings while I'm in there).
