Yesterday I hooked up the van for the first time to the truck and also fitted the motorbike on the back of the truck to see if everything works out. The front legs are not on yet and the chassis is a bit higher than ride height. We finished all welding on the thick stuff, completely done and use one 7kg role of wire so far.
Today I did put all legs back on and wired the electrical connections. Takes some time because I had to cut the harness provided (just way too long) and fit connectors. Waterproof connectors take time to fit, lots of little bits and pieces.
