I was up there too! You might have seen me - on an orange KTM motorbike (along with about 100 others, mostly on orange KTMs, who attended the annual Big Bear Dual Sport Ride). I hope to post a picture or two soon.
Wife and I really laughed about the barbecue and lawn chair on the inflatable SUP. Don't melt it! We think about getting inflatables, as our hard SUPs and sea kayaks won't be easy to load on top of the new high-roof Sprinter. Now that we see how easy life can be on an iSUP, it sounds even better.
