Feye, I was having the exact problem you describe on Duna, using a lightly modified "Butterfly Rover" from the set of stock vehicles (it's an option to enable them when you start a game). Using your hint to use F3 to figure out which things were consistently getting the 'structural link failures', it was always the propellers first (that rover has 4 wheels but also two rotors for extra speed). I tried locking the motors at zero RPM, still exploded. Then I used an engineer to disassemble just the rotor assembly (remove the propellers and the rotatory engine). After that, no explosions! Was able to nav to all the anomalies on Duna, which was awesome.
Always travel with an engineer! Never know when you'll need them :-)
Thank you to the mod authors! This amazing.
