The Truck ESC weighs 2x what the Pro does (around 120g). To be honest the heatsink makes it very bulky, but I like the extra insurance it offers. You could get away with the Pro no problem. The Truck in my opinion does have slightly different internals - at the very least it has different software, I know this because when I mentioned to Mtroniks I planed to run mine on low voltages for a while they offered to load an "optimized" version of the software, based on the Pro software onto it. Turns out after I got the ESC and ran it, there's no real need as its just as smooth as a Pro anyway.
It sounds like your best off with a 380-L motor. A 380C 7t or 8t will not offer more torque than a 6t, it will just rev lower and give less power. I have a 380 8t and 9t, and have heat issues with them after 10-15 mins of running on 7/8 cell batteries when geared for around 40mph in my truck (which weighs around 2.5kg..so maybe a bit heavier than yours).
At the end of the day even if you get a 380c-6L and decide you don't like it (which I find somewhat doubtful), they're worth a very good amount on Ebay. It will be quite a bit more powerful than your SS5800, but should offer very nice runtime as well. With my 380 8t (same kv as the 6L, but shorter can which is why I have heat issues) I was always getting 10-15 mins runtime (which is good, if I had any more, the motor would have overheated!).
