I would be worried if I had a big massive coach with granite tops and marble floors. Some of these luxury coaches that have all the amenities you can think off weigh a lot. So the carrying capacity is cut down to where you got to watch what you load and carry in those compartments.
But the ordinary coaches with the corian countertops usually have great carry capacity.
One coach that comes to my mind that has very little CC is the Beaver Marqui. Everything on those coaches used to be very heavy.
But entry level coaches are not very heavy, and what do ordinary RVers carry anyways. Reclining chairs, BB grill, outdoor carpet, a couple of folding bicycles, a tool box, brooms and mops, cleaning supplies. etc etc.
The thing is that all this stuff ordinary RVers carry do not amount to much weight. What weighs a lot are the fuel tank, water tank. Most of these luxury or big coaches are designed very poorly. Once they get all that junk into these massive coaches, the CC is gone. So in my opinion those are the owners that have to watch the weight on their coaches.
