We picked up our SMB at the beginning of the winter, and as we live in Wyoming haven't gotten to take in on the road, until Spring Break.
After the first trip, we're excited to dial our setup and streamline the setup/breakdown (not much built in storage in our setup and we've got 2 kids tagging along with us).
Probably the top of the very long list would be roof box, galley or other box on back, getting the ladder put back on (a whole other story,
), and improving the bike rack situation with a swing out hitch adapter and probably some 1up bike racks (saw a bunch down in Moab, seem to be the choice for off road use).
I've already gotten good general information from the threads, and look forward to getting more specific now that we've got wheels on the ground, so to speak.
