When I was building my Troy base on Duna, I sent two components to land in roughly the same location: one habitation module, and one power station. The power station was equipped with wheels and was to drive towards the other module and attach itself by the docking port in the front. However, these wheels broke on impact, and the power station was rendered completely immobile - two kilometers away from its destination. With no Kerbals around to repair it, I had no choice but to improvise. So I took the Surveyor rover I had sent earlier to push it in place instead. It was a slow and tedious process, cruising between dunes and taking detours all the time, but eventually it worked out, and Surveyor was renamed Stallion in recognition of its hard work
