I find it interesting how you appear to be more concerned about rare potential off gassing than on your other thread Comments about truck weight ratings more often being to reported to low for potential legal reasons. That it could be OK to overload the specs, on a daily basis.
I do agree that both truck and rv manfacturers need to be more transparent about how they report weights. It is all mumbo jumbo.
By the way which weight rating would you follow. The lower camper certification weight or the higher pillar payload weight?
