Yes very impressive. And here I have been patting myself on the back for successfully converting from our failed SDS2 cooktop to the D21. This guy just deflated me.
I don't remember if he addressed trailer weight but that would be an interesting tid bit which could probably go either way. My guess is it might be on the heavy side. Our 21C weighed 4525 lbs loaded for a 6 week trip from Kansas to Newfoundland and back. I see myself remaining not as intelligent and industrious as he is, not doing the research, self-educating, and exerting elbow grease required for that level of modification. Just sayin'.
