Now this might be a hidden update but nowadays it seems my mtus are bagging less of the nice large rail guns from wrecked npc ships. At this time we have about 2.8billion in loot about 350,000m3. I usually get about 2.4billion from 250,000m3. Oh well good thing I have a bpo that I am currently researching, and I have so many mtu's now between yogi and I, we have around 30+. I hope to increase this number as yogi and i can complete anoms soo quickly perhaps once or twice a week we can deploy all of them at once! Carrier ratting for the win!
Some information on mtus once again taken from eve uni's wiki page!

Mobile Tractor Unit

A Mobile Tractor Unit reaching into the depths of space to pluck the most succulent fruit
A Mobile Tractor Unit (or MTU) is essentially a massive cargo container with a tractor beam bolted on. Once deployed, it uses a single tractor beam to pull in any wrecks and cargo containers. It has a range of 125 km, with a 1,000 m/sec tractor velocity, and a 27,000 m3 cargohold. Deployment time is only 10 seconds, and the MTU will last 2 days in space before despawning. The MTU is only accessible by its owner. When destroyed it drops partial loot the same way a destroyed ship does.
The MTU may not be deployed within 5 km of another MTU, within 50 km of
stargates or stations, or within 40 km of a
player owned starbase. It has 50,000 hitpoints. However unlike the Mobile Depot it does not enter reinforced mode and can be immediately destroyed. Like the Mobile Depot, the only consequence for shooting another player's MTU is a Suspect flag; CONCORD will not intervene.
The MTU targets the closest item first, tractors it in, and loots it. Due to the "closest first" behaviour, you can't use more than one MTU per site, as they will interfere with each other and pull nothing in at all.
The MTU has become extremely popular despite its cost, particularly for looting
mission rats. Though not as fast at tractoring and looting as a
Noctis, the MTU continues to loot a field even when you're not there, and deposits wrecks in an
easy-to-salvage group around itself. This can allow your mission ship to salvage while running the mission, using either a utility high slot, or salvage drones.
Some systems have seen an increase in organized griefing centred on Mobile Tractor Units. Similar to
ninja salvaging and stealing, a gang will take up residence in a
high activity missioning area and scan down MTUs. They'll then aggress the MTU, attempting to bait the missioner into engaging them. As with ninja looters, the options for dealing with them are fairly limited. Engaging the griefer will set your engagement timer and their friends can warp in and finish you off. Not engaging will cost you both your loot and the
cost of the MTU. Orbiting the MTU at close range mitigates this heavily. As soon as you see them warp into your pocket you can empty the contents of the MTU into your hold and scoop the unit. They will be left with a mission pocket that you have already looted and are likely to move on.
MTUs do not loot wrecks that are not yours. There are some griefers that prey on this misunderstanding. After arriving in your mission pocket they may drop an MTU of their own hoping you will engage it, presumably because you think that it will collect your loot for them. It is best to ignore these rogue MTUs as they won't affect you. Even if the griefer warps out and leaves it behind they can monitor you in local to see if you've become a suspect, and warp right back in with friends.
Variations
There are two variations of the MTU, the 'Packrat' Mobile Tractor Unit and the 'Magpie' Mobile Tractor Unit. The Packrat variant has a larger tank, while the Magpie has longer range. Both have increased tractor velocities, but the Magpie has the fastest. Both also have increased sensor strength, making them harder to scan down. Both are considerably more expensive, with Magpies running at hundreds of millions. The
BPCs for these units can be found from
Ghost Sites.
