Good catch on the Meerkat - Eriba Puck similarity. They seem quite similar. This thread and post from someone familiar with both Says the Meerkat was at least inspired by the Puck. Appears they still make Eribas, maybe not Pucks:
"I miss mine but must admit, like my Meerkat now. It is very similar as it was designed from it but miss the back big tilt window. Meerkat has sliders. Also miss the table design of Puck versus Meerkat."
Meerkat's site says this:
After years of being a dealer for many smaller trailer brands new and used, we came to the conclusion that no one trailer fit our specific camping needs perfectly. We then adopted ideas from many different trailer lines new and used and developed the MeerKat. We wanted a stand up trailer that would fit in a garage and weigh in at less than 1,000 pounds. We wanted a hanging closet and comfortable bed with cooking capabilities, and an Icebox. We also wanted good ventilation."
In England, Eriba is part of the Hymer family, the German company that acquired Roadtrek vans in Canada. Hymer has lit a fuse in the Class B van category. I've seen references to 1951 Eriba Pucks, 1968 Pucks, 1988 Pucks, and they appear to be in current production.
"We're the Russos" is an entertaining YouTube channel by a couple of nerds fulltiming
in a very nice Hymer. Here they tour a Hymer with a Westfalia style loft bedroom. I have fond memories of a Westfalia, but not fond enough to want it back. The new tall vans are a huge improvement.
Beyond this, I know little. ...Back to Hunters.
