Lepin Baja Trophy Truck (23013) Build / Lepin vs LEGO Comparison

I’m  just taking it down another path.     You can also find published instructions if you want to build it yourself.  For some time, I wanted to get an RC crawler, but they can be $$$.  When I came across PunkTacoNYC’s Chilli Crawler, that was I figured I had...
