DSTs slow and not very agile. That means even with all the stabs and MWD+cloak trick, you're not going to get into warp all that quickly and all it'll take is a good bump to ruin your day. And when that happens, all that EHP isn't going to mean very much because you're dead anyway.

If you really want more space than BRs provide, I'd probably just use a large T1 indy. You can still MWD+cloak trick with them, but if you get caught, you won't lose an expensive ship.

But really though, I'd just use a BR. They work very well for lowsec purposes.

except when i need to transport cruisers and dont have the time to train for a viator.

The DSTs are wayyy to bulky to successfully pull off a proper MWD + Cloak trick without sacrificing some slots of agility mods. IMO the best ship for this job are the 'light' T1 Indies, not sure what it is for Gallente, but Badger, Wreathe and Sigil for the other races. I haven't tested the other races but I've been using the Sigil extensively for lowsec hauling and it can easily carry a packaged BC and if you're good with teh MWD + Cloak trick, almost uncatchable except maybe insta-lock T3 camps, however the route I ran never had any of these but I did run through a couple of rag-tag gatecamps in my Sigil. Since you're using Minmatar indies here's how a similar fit Wreathe would look like:

18.6km3, aligns in 8.53 seconds with mwd on, 5ish without.

Yes it works with low nav skills as I've been doing it on my alt which has only 30 days worth of training on it, most of which is in spaceship command to be able to fly the cloaky hauler. However your window to do the mwdcloak trick successfully is quite small. As for which hauler has the most, I'm unsure, the wreathe has more than the sigil, but I'm not sure about the caldari and gallente as I don't have eft handy right now.

I run this as my primary low sec hauler, it can move even BCs with fitting -> 17km-¦ cargo, is smart bomb BS prove(very good emp and explosive resists on shields with over 4k shield), I did even run into a dual smarbomb BS camps and passed this without issues, can take every jump without capping out using claok/mwd at gate(this is what the cap battery is for) and could even take one volley of a Tornado in Empire. The probe launcher also allows full WH capability, what is kind of nice. Without shield upgrades V you need to use a meta 4 extender.

Djego brings up a very good point, his fit is actually better than mine, it is more optimized for lowsec hauling, especially the smartbomb camp resistance as I've run into a single BS smartbomb camp before and I ended up in low armor, so 2 BS would have easily taken me down. Also capacitor is an issue on my fit with low skills, constantly using the MWD + Cloak trick + systems with long warps can force you to need to stop and recharge cap to prevent capping yourself out.

The fit I use is on an alt I use on my same account for hauling stuff to lowsec cause Dato can't go to highsec, I activated 1 PLEX on her which was just enough for basic navigation skills and the ability to fly transport ships, so I can't use T2 Invulns, extenders, cap batteries etc.
