Weigh the vehicle

How much does a motorhome weigh? This question could determine whether we continued our journey or received a fine. So far, we hadn’t experienced any police checks with Gary. In fact, we hadn’t been checked for years with any of our vehicles. However, should it ever come to that, it would certainly be wise to know how much our Gary would weigh. There were plenty of other things that would play a role during a check: papers, first aid kit, life vests, lighting, breathalyzers... all of that could be checked on our own. But weighing a car? The police could do that, and they did. Who else could weigh a car?
In Gary's papers, there were two numbers. In field F.1, 3100, and in field G, 2360. So according to the papers, we had an allowable total weight of 3,100 kg and an empty weight of 2,360 kg, which meant we could load 740 kg. That sounded quite generous, but was the empty weight accurate?
Sebb couldn’t let go of the question and he asked at a TÜV service point if they could weigh the vehicle just once.
“Just weigh it?” was the reply.
“Yes, just weigh it.”
The friendly TÜV guy noted down the numbers and in not even 2 minutes he was finished. Now came the moment of truth. Front: 1,310 kg, and rear: 1,280 kg, which added up to a total of 2,590 kg. That was 230 kg more than what was stated in the papers. Well, we had just refueled, there was also some water in the canister and some luggage in the trunk, but Ines hadn’t been in the car, the fridge and the cabinets were still empty, and only one gas bottle was on board. Would 510 kg be enough? Would we have to weigh again when we were fully packed?
We converted to beer crates. A 20-pack weighed about 20 kg, so at 500 kg that would be 25 crates of beer. That should be sufficient.
