Donated professional services to a good cause.

I was half selfish in that I camp with this buddy all the time, and wanted to see what off-road trailer camping looks like. My other buddy bought a $50k Vorsheer trailer and he's loving it too. But the honesty and ease of use of the smaller trailer makes the big one look excessive, and not necessarily for the better in many ways. Smaller lighter gets though stuff in ways that bigger, badder, can't. Sets up easier too.
That's true for the tow vehicle too. Something smaller like the GX can have some significant advantages depending on the region/trail.
It was closer to $1.5k after adding a water tank and custom axles. Not including the RTT and awning/room as those are another $1k+ in goodies.
