Spot on .... the answer is for us both to visit weight-watchers !!
But, need to use the van this year and willpower is somewhat lacking.
The van is a 2017 Dethleffs Globebus T7, rated at 3500kg, and with a stated payload of 500kg. However, by the time we take off the weight-watchers candidates, plus the spare we've added, plus table/chairs etc and plus some water for traveling between un-serviced Aires in France, not much left for beer and wine
Am sure the up-rate is the way to go as much of the fun disappears without being able to take the kitchen sinks etc.
