Who are these Micromasters?

I recently bought a combined lot of assorted G1 Micromasters and accessories (and yes, it in fact includes one Actionmaster vehicle). I've managed to identify most of them, but the three circled Micromasters remain a bit of a mystery to me, though. Not even TFU.info or TFwiki can help me identify these ones. So perhaps you can help? (Apologies for the bad quality: pictures taken by the seller. They are clickable to a slightly larger size).

Best shot of the grey and black Saab Grippen Micromaster. It's evidently a repaint of Skyhopper (grey / pine Saab Grippen) and Storm Cloud (lilac / back Saab Grippen), which are placed next to it, but neither TFU.info or TFwiki have info on other repaints than these two.
This one is solved: it is most probably a VERY yellowed Storm Cloud(!)

Best shot of the black / dark green Monstertruck. Again, this is evidently a repaint of Mudslinger (blue monster truck) and Greasepit (grey monster truck) which are both also in the picture.
Again probably solved: it's most probably a very yellowed Mudslinger! These guys must have worked at a tanning salon on the side! It might be interesting to see what peroxide will do...
Still remaining, who is the blue truck? It looks a lot like Dropshot from the Decepticon Military Patrol, but the painted windows and the blue gun don't match Dropshot's colorless body and grey gun.
