Liberty Outdoors has discontinued production of the Parkliner
. There might be a few unsold units left on Little Guy dealer lots if you do a nationwide search. Other than that, your only option is used.
Note that there are two versions. The older Parkliner 15 was made through 2016, I think, and the newer Parkliner 16 was a one-year wonder in 2018. The cabin and layout are basically the same, but the new model has a full fiberglass interior and a number of other design changes. It’s somewhat heavier and quite a bit pricier.
Hopefully a nearby owner will chime in and offer a look-see.
