Question 1: Either none at all or at most one.

Question 2: 3, 6 with upgrades as usual.

Question 3: Yeah. Actually, if you want you can base it off of the design I built.

Question 4: I honestly have no opinion either way on this. Maybe a boat of some sort that could be used to take out rock monsters from the water, but it's ultimately up to you.

Question 5: Make the Hover Scout able to cross water, and up the speed on the heavy vehicles (Chrome Crusher, LMLC, etc. Anything on the heavy chassis).

Question 1: If it has a cargo area.

Question 2: However many ores and/or energy crystals would fit in that volume of space, without exceeding the max carryweight of the vehicle (including the driver and the vehicle itself)

Question 3: Yes, make it a freighter or equivalent. Maybe a hoverscout-like freighter. If a freighter (semitruck) in real life can hold cars, I'm sure a freighter transporting energycrystals and ore can hold a ton.

Question 4: ...Don't know. I'd like to see more hover vehicles, but whether or not that'll fit into the game depends on the game.

Question 5: Nothing comes to mind at the moment.
