Convoy to cross China in a 4x4 camper van, September-October 2025

My Thai wife and I are planning to reach the Laotian border with our 4x4 camper van in 30 days (no visa required for Europeans) via Lhasa in September-October 2025. Our vehicle is currently parked in Kyrgyzstan, and we're looking for candidates to form a group of 5 vehicles.
