What the ratings say
B-21 Storage is the one most people point to, with 45 reviews and a 5.0 average. It is also the only indoor option in town, and it throws in a gate, cameras, climate control and 24-hour access. Stor-It-All sits at 4.8 over 10 reviews with 24-hour access. The two Storage City locations have a single review each, both 5.0, so treat those as thin evidence rather than a verdict. When a place has just one review, call and ask about gate hours, unit size and whether the lot drains well after a spring storm.
Indoor versus open parking
With no covered spots and only one indoor facility among the four, most rigs in Box Elder sit out in the open. That is fine for a season, but western South Dakota sun and hail do not go easy on roofs, decals and tires. If your coach is older or you are storing through winter, the indoor unit at B-21 is worth the call. Otherwise, plan on a cover, tire covers and a good coat of wax before you park it. Ask each lot whether the surface is gravel or paved.
Around Box Elder
The town runs right up against Ellsworth AFB, and Rapid City is a short drive west, so a lot of storage customers are military families, snowbirds or folks who split time between here and somewhere warmer. That means turnover can be quick and the good units do not sit empty long. Book ahead if you are moving in over the summer. Nearby places to check while you are in the area include the base, Rapid City and the Black Hills beyond it. Two of the four facilities give you 24-hour gate access, which helps if you roll in late.
