Hi this year at the BOCI Rally
, this topic came up as the owner of Bigfoot
was there with a couple of guys from Bigfoot
. Talking to Rob he said that they have had as much as 5 men on top of a Bigfoot and they did this at a RV Show just to show the strength of the Bigfoot roof, so I don't think that you have anything to worry about, and yes I am 200 lbs and I go up to wash, check vents, check caulking, and to install my winter cover every year for the last 10 years and there are never any weak spots.
