Sorry. Have an exam tomorrow that I've been studying for. Once that is done and the weekend is upon me I'll be sure to post.

Don't push yourself to post at the cost of something else as there will be time to.

Edit: 
I'll also weigh on the truck issue:
If the trucks were going in 2 lines and one could manage to get in middle of them it just might be possible because the FRAMEs we pilot are 4.1 Meters for Zaruga and 4.3 for handou. Here are dimensions for a normal truck in meters:

So at least the height should not be problem (unless dreq was much larger). It is true though that one can't get "behind a truck" if they go in a single line.

Edit2: for Dreq size, I got a picture of it next to a excavator facing the camera. this particular is for a specific character and unlike other such mechs would, he carries melee weapons.

(could not find pictures with measurements for excavators)

Edit3: I have no authority over FRAME sizes but I confirmed the former sizes from OP and it corresponded with source so I thought it was worth the effort. [@Aristo] can correct Dreq size if it should be different in universe and what [@Aristo] says will be how it is.
