After talking about it we decided to do it, today!
A young friend of us, Art from Chiang Mai on his D-Tracker and my wife and me went by pickup to Chiang Khong, Art tried crossing solo over the bridge, no luck! We waited for him at the coffee shop and loaded the D-Tracker on the back of my old Isuzu.
So back to the border crossing and it was "no issue", however quite a lot of paperwork was needed and staff seemed a bit confused. When at the customs booth it was said they never did this kind of combination yet.
At the crossing I ran into forum member Lipmeng, all the way from Malaysia with his Africa Twin, we had a very pleasant conversation as he is a cheerful and friendly, but unfortunately he was also not allowed to cross the bridge solo and went to cross at Nan.
Over the bridge and into Laos, less paperwork but slower at work, in the end all done and into Houei Xai. Picture time and some boxes of Beer Lao later we went back over the bridge.
Again process at Laos side not many questions but slow and at some costs.
Thai side smooth but unfriendly, in all 4 hours up and down.
Total costs about 1000 baht for my car up and down, 1000 baht for the bike and 1400 baht for my visa.
