Thanks for those info!!! Now there will be no more confusion about these vehicles.
What lvl do you recommend to get the steamboat design? I really want it!!!

And it would be nice if you can collect more vehicle designs, and make a full set.

What do you think? Which level will you recommend to beat those 4 wolves? You need to beat those wolves for the steamship design.

Sure, if I find more designs, I will upload them to here.
