I can only comment on the TAUCK trip which i just came back from. We saw several other tour company vehicles while on safari. ALL of them had tiered seating, ALL of them had canvass tops.

ALL of our transfers were on Cessna's...NONE of them weighed ANY of our bags. When we filled out the paperwork, They asked for OUR weights...but they never weighed us. I cannot address any other tour company rules or regulations. I can only discuss what happened on OUR tour.

While on this trip...we had 12 flights.... Four from STL to Livingstone, one from Kasane to Khwai, one from Khwai to Eagle Island, one from Eagle Island to Kalahari, one from Kalahari to Maun, One from Maun to Cape town, and three from Cape town to STL and our bags were weighed in STL and in Maun and in Cape town....and those were international flights on jets.
