Tadpol Chasis Upgrade

I recently finished the Early Access portion of Subnautica 2 and I loved the upgrade that the Scout Chasis brought, It felt like I was actualy improving my Tadpol and progressing in the game. When I found the first fragment of the Haul Chasis I was really exited for the new addition, but when I finaly constructed it, it turned out being really underwhelming. It took 3 scans, lots of resources, It was sooo painfully slow (felt even slower than swimming), and didn’t provide any other use or upgrade other than the storage becuase I played in single player modes so the upgraded seats didn’t do anything usefull.
What I’m sugesting Is that the Chasis themselfs can have upgrades that you discover, craft, and equip (like the Tadpol upgrades). For the Haul Chasis it could be a new speed upgrade or double the inventory space, this would prevent the unuse of the Chasis becuase it was so slow or give an even greater reward for pushing through the speed. The Scout Chasis could have upgrades like increaced agility (even more avalible movement), or the ability to glide through the air after launching out of the water.
I feel like the upgrades sould still maintain the purpose of the chasis, like it wouldn’t fit to have a storage upgrade on the chasis made for speed and agility. But it sould help maintain the relivence of attachments like the Haul Chasis that I only used once in my early access playthrough, It would also bring a further feeling of improvement and of conquering the waters late game, to match the feeling of constructing the tadpol for the first time.

i made it once, and used it to carry the stuff to the power gen to repair it in the frist play though. i havent made it since since i need speed over hauling, the one box on the back is enough for me. i play solo xD
