B96 or light Where to look?

Evening. After 3.5 years of camper and a year of camping break, it thirsts us (5 persons + dog) for camping. The reason for the sale was the lack of mobility on site. Due to a misadventure in the late 90s I have only class B, while my better half has B1E to 12t. If I now look for WoWa with 5 sleeping places, then these are mostly between 1,300kg and 1,500kg zGG. My car has 2,250kg zGG with an empty weight of 1,670kg, a trailer load of 2,100kg, a support load of 100kg and a payload of 580kg. As soon as the WoWa comes over 1,250kg zGG, I exceed the 3.5t GG of tractor and trailer. If I have understood all the contributions correctly, I deduct the payload from the payload. Are then 480kg. 2 adults, 3 children, 1 dog should be with us about 300kg. So stay 180kg in the car for luggage etc. With B96 the team can have 4,250kg zGG. So the WoWa smooth 2,000kg zGG. The 100 registration would exist up to factor 1 of the curb weight of the train Now we are faced with the question whether we should look for a WoWa up to 1,250kg zGG or if I should extend my cloth by B96. At the moment I tend to B96 with a WoWa up to 1,500kg zGG. If there is still an awning and a few camping furniture to the clothes, the WoWa should not be sewn on edge (useful load). Are there members who also made the B96? Many recommend the hanging certificate with examination. But so much effort for the few Fa Did you have a year? Oh, if the train car is no longer, a similar or similar one comes, which has about 5kg less payload. All of you a quiet new week
