I researched several locking mailboxes for the benefit of 104 homeowners in my neighborhood. I did a careful hands-on comparison of the Oasis [not Oasis Jr] and the Mail Boss (see disclosure below). Advantages to each, but I preferred the Mail Boss overall.
Advantages of Oasis:
- - Hopper style door will accept some thicker packages up to appx 4" x 6" x 12". Mail Boss max: 1-7/8" x 10.2" x 14.5"
- - Similar Capacity: appx 1400 cu in. (but Oasis has appx 28% more capacity than Mail Boss at hand-fishing limit. See below.)
Advantages of Mail Boss:
- - Much more pry resistant. Thicker steel (14/12 gauge vs 16/14). Recessed door top. Heavier lock, Hook-style lock tab.
- - Clean look. Not too tall (14" vs 20"); Looks OK mounted next to smaller mailboxes
- - Includes 3 keys and reflective address numbers (vs 2 keys, no numbers)
- - Slightly less expensive
- - Wind-blown rain: Mail Boss protects pretty well using inset door-tops. (I tested it with a hose.) Oasis has a protruding door top with a rubber seal, which will easily take in water if its rubber seal degrades. I like the Mail Boss design better, but would probably add weatherstripping for "belt and suspenders" protection.
- - Rust: Either box will rust out eventually...(Avoid white model.)
- - 10"x13" envelopes hang in the mail slot due to textured mailbox floor (like most other mailboxes) (add smooth cardboard to rear of floor)
- - The Mail Boss has a Mounting Plate system for easy installation, but not an issue vs the Oasis. Oasis has about 10"+ of vertical clearance inside the box -- probably enough for your cordless drill/driver.
- - Workmanship on both mailboxes is flawed, but acceptable
Prying and "fishing" are the two main concerns. Fishing means reaching in and pulling mail out through the slot. No evidence of tampering, so you may not know whether some of your mail has been stolen. Tested with my arms, which are just a little thinner than average adult male arms.

Disclosure: The manufacturer of the Mail Boss sent me a free mailbox for review after seeing my amazon review of the Solar Group RSKB0000 Curbside Locking Mailbox. I feel this is an impartial review. I have no connection to any mailbox manufacturer.
