Remember we are talking about class B's. I do take what I think we will need but no more. On other hand lot of his stuff is for RV parks (cable, lights, etc.) and those are not our style and we avoid them as much as we can. And of course his B is based on a Sprinter while mine is a Chev Extended van. I think all my "essential" stuff would fit in two of his plastic containers. That does leave space for 'comfort' stuff like folding chairs, rug, folding table, dutch ovens, etc.
Well maybe on second thought he might have twice the amount of stuff not ten times. I don't have the leaf blower but I do have two tow straps (I needed but did not have on Newfoundland).
