Hunter made 3 models. The Compact Jr. Is a smaller and lighter trailer with a different shell- narrower and boxy- with a full length pop-top. Sleeping is lengthwise on a generous 70"x72" front dinette bed. The rear galley is small.
The Compact I and Compact II are built using the same wider, clamshell-style shell with a shorter pop-top over the rear galley only.
The Compact II has more cabinetry, more appliances, and a toilet closet with black tank. The U-shaped front dinette makes into a transverse double bed.
The Compact I (seems to be the rarest of the three) is more basic with a smaller galley, no toilet, icebox, and (I think) a larger dinette bed.
All three are great 1- or 2-person layouts. Rear entry makes for excellent space utilization, but they can be somewhat tongue light
As with any vintage trailer, value is quite variable based on condition mainly, along with location and season.
