Avoid the fastrax hauler at all costs, even free ones... they are terrible and a total waste of money. parts of mine were replaced 3 times in a year, outer zips failed multiple times, handle failed twice. just avoid.
I'm on an ogio 9800 now and its fantastic. its perhaps not as convenient as a hauler, as you need separate tool/parts bags and boxes inside, but for me it carries way more than the hauler did, and in an easier to manage/roll/carry package.
I use an arrowmax tool bag for my main tools that go on the table top, which has been awesome. still going strong after 2 years use. its used most days and is always on my desk at home when i'm not racing.

I use "reallyuseful boxes" in the ogio for parts and more tools and stuff, two 4L low profile boxes.

For Oils and fluids i use the 3L higher profile box:

For parts/screw trays I've got:
A few of these low profile parts trays from LMR:

and I've a bigger parts tray from B+Q.
Transmitter goes in a hobbyking box:

I want a setup station bag, which will will save me some space.
Tyres go in a big 18L really useful box (which doesn't go in the ogio):

Or in a carrier bag, depending on which ones i take to a meeting.
I don't think I've missed anything, but it works for me. I found the hauler far too bulky to carry upstairs, and just awful in the back of my car, where as the ogio sits nice and low.
You could get a decent heavy duty work bag, as has been suggested if you
