Not quite sure what sort of response you're looking for but here goes...

Trukk boys, yes.

Gretchin, assuming they are a meatshield for Lootas?

Looted wagons, soso... you have a couple and with the trukks being in their face they should last more than a turn. So okay

Lootas, yes.

Big mek, okay but unsure why he has a power klaw. Assuming its for the chance he teleports himself into CC, but if that happens hes attacking at I1 and so would probably die before retaliating. Would suggest dropping it.

Deffkoptas, dont feel they bring much benefit with big shootas. You have enough to deal with infantry at the moment so probably want to get them TL rokkits so they can get some side shots at vehicles when they outflank.

I'd suggest dropping the grots and power klaw. Then depending on how you value your lootas, either take an ADL or upgrade all deffkoptas to have TL rokkits.

Haha, yeah I always seem to be on this at weird hours...

Anyway there's no reason the gunline/speed army wont work. However there is one particular weakness to it and that is deep strikers and outflankers. These could make short work of your lootas and if they are MEQs, lootas would struggle to knock them all down unless you're lucky. As the trukks rush forward it leaves the lootas exposed so I'd still suggest getting an ADL. I agree with using the grots as a mek meatshield so here's what I'd change:
If you outflank all rokkit deffkoptas and they turn up, each has a 5/9 chance of hitting so thats just under 4 hits a turn between them. At ap3 they offer nothing on the damage table and at S8 they only reliably damage light vehicles. I would loose two for 90pts. Give one kopta from each unit a power klaw for 50pts in total. Note these are only S6 and S7 on the charge, but seeing as their main target is light vehicles, 3 attacks that may auto hit at ap2 are better than one 5/9 chance of another S8 hit. The nobs in the trukks would have to deal with anything harder regardless.
Then if you dropped the klaw on the big mek, take an ADL, that will improve the longitivity of your lootas immensely. That can pretty much make them terminators when being shot at. For the last 15pts a rpj on each looted wagon as every 1" you can get on those pie plates are valuable.
So
Hq
Big mek, Shokk attack gun - 95
Fast Attack
2 TL rokkit deffkoptas, one pk - 115
2 TL rokkit deffkoptas, one pk - 115
Heavy Support
Looted wagon, boomgun, rpj - 110
Looted wagon, boomgun, rpj - 110
Looted wagon, boomgun, rpj - 110
and the rest
or if you still want the pk on the mek, for the 40pts just make each looted wagon 'ard case so it doesnt die as easily

I thought you rolled to see which weapon was destroyed?
