Was just thinking about junk turrets, how, at least other weapons, they have their own advancement system to better weapons (Pipe shotgun to double barrel to pump, to auto, a Baton to stun baton, etc.) and that junk turrets/sledge turrets could have their own advancement as well, such as turning them into a mobile turret with treads, and the finally hover, so a more focus on them via mobility. OR, if we wanna keep them as a immobile turret setup, a visual change of it being more refined and less trash-looking until it looks more like a military-esque turret with armor, more accuracy, ammo, damage, etc. I personally think the mobility form of advancement would be far superior, especially for a sledge turret.
