Are there any reasonable chest farms anymore?

[Kuusou]

I'm just looking to farm chests while a friend is offline, are any of the areas still viable? Or are they all patched?

What are "any of the areas"?

I presume you're not talking about the Armory :-) I've always liked the chests in Crimson Fastness; usually entered from the exit so I would immediately be in that room with the 1-2 chests and the 4 badasses. You can go to the other areas from there as well, of course.

Sledge's Safehouse also makes a good farming area: there is one chest outside, one where the claptrap was, and one in the room opened by the claptrap (plus the lockers there). All this is accessible with just a few bandits in the way that you can just as well ignore.

New Haven has a bunch of "free" chests hidden inside the town, but those are white. I don't think they are worth it.

The Underpass: take a car and drive down the road to the bridge. There is a hut there on the left, home to a single badass bandit with a red chest. Also one of my favorites.

Unsure as to what type of farming you want to do. Since I've maxed my Siren level and have pretty good equipment I farm when I want to, Crimson Armory using the still working glitch. Or there is the chest room after beating the Robolution DLC (not as good though). Other than that what Kargor has said are also nice areas to farm. I like Sldege's Safehouse.

For instance, New Haven used to be a good spot, but all of the chests were patched over. I wanted to know if there were good spots that were not patched over, and are worth doing over and over.

Well, New Haven chests have probably been toned down because they are just sitting there in town.

Every once in a while you DO come across chests that are still red chests, but can be reached quickly. I already listed the ones I could come up with quickly because I've visited them a lot. And sometimes these are "better" than the Armory simply because it takes quite a while to even get to the Armory, whereas making a trip to Underpass before going where I want to go is more feasible.

Also, an IMPORTANT part of farming has always been the shops. Shops are exceptionally good for providing (non-DLC3) class mods and shields (the class mod I'm using came from a shop, and it's a perfect (i.e. all max) ammo regenerating Mercenary; don't remember where my shield came from). Shops can also provide purple and orange weapons; my very first legendary that I found (but I didn't use it) came from a shop.

I'm not too fond of the Hyperion Gift Shop, but that could be because the very first DLC4 that I did was the PT2.5 at lvl 69, so maybe I just didn't care that much about the shop. I did get the impression that even though the chests are red they have been toned down, possibly for similar reasons as the New Haven chests. But that's just a feeling; it's not like the game gives you any indication of special chest parameters other than the chest type itself (white, red or lance).

There's also a hidden chest reachable from the Underpass waypoint, but it's hard to describe. You basically just race through a bunch of enemies (effectively ignoring them as they won't follow you anyway), onto a rocky ledge, jump down a cliff and get into a cavern with a chest. That chest is just an ordinary red chest, though, and it's a one-way trip (so you have to quit the game to get out, or die). I have occasionally done some "Underpass farming" -- checking the shop, getting the badass chest, then getting that chest, then quit and reload.

As a side note, during PT1 I *have* identified a special red chest, in that bandit camp on the mountainside with the bridge across the gully, where one of the 'get the weapon parts' quests is located. There is a chest that provided Lvl 20+ items, at a time when this was still in the far future. That chest is nothing special in PT2, though (as far as I can tell), it's just that the level is way above the normal level for that area in PT1.
