Best engine car combo for a car train?
Personally, I'm very happy with a Poyopa with a twin turbo Muskgoat engine.
I thought the Poyopa will be a good truck for hauling, but the engine is too weak. Then I thought, "Let's slap a racing engine, and hope it survives." Surprisingly, it works very well.
I'm trying to get the new cars - at the moment, I'm towing 5 of the reskins, and even on inclines, the Poyo-goat hybrid is doing well.
What other combos have you found to be good?
