BTW, it is possible to let your Marstruck (and later Rover) battery module(s) be charged in the battery rack... besides one row of suit batteries, there is space for 4 vehicle battery modules. So if you like, you don't have to connect vehicles by cable, and you can even have spare battery(es)... range extended, if you take charged spare with you...
Hm, are you aware that Sabatier module (well extension) decreases the water production? Making oxygen this way is quite ineffective... just ONE Scrubber produces more (and as side effect, fill your CO2 bottles, too). Oxygen produced by sabatier is only needed to refill Rover (or Jetpact) and quite small amount at that (5hr production of 1 module enough for refilling Rover)... Normally, you don't need more than 1 extension module.
