Where do we find the weight distribution for 5 th Wheelers. And how it is worked out??

all I can say is there are by what we have seen so far , a huge amount of people out there towing way heavier vans than they should. The amount of gear people have mind boggles us at times. We don't have much at all. But I want wardrobes, recliners, a separate dining, separate bedroom. There are some Australian ones that do have sliding wardrobes, 5Th Wheelers that is and they and cell vans are the only ones with room inside. Caravans don't, and we are not people that tend to pull up at a place, unhitched, put our chairs out and sit outside. That has never been our life, only outside when having a bbq, and entertaining. The rest of the time we are inside with our animals, and I am doing my jigsaw puzzles, or on computer sorting out photos or chatting to friends via Skype O/S. So our life is a little different to what we see is the norm of caravaners with their happy hours, running to meet at others vans etc. we travel alone, and know no one on the road, unless we chat to people in a park for a bit. We like this life and most probably won't change.
