Ok, I'm full of it. But here's a fun fact. The closest thing out there to my list is probably the Jayco Hummingbird 16MRB. Reasonably comfortable sofa/murphy bed, and NO DINETTE. Wastes a bunch of space on a giant dry bath, but can at least claim an actual closet. Barely towable by an SUV.
As near as I can tell, there are a grand total of THREE for sale in the entire country.
It's no longer made. It was replaced by the Jay Flight SLX 154BH. Bunk beds for the kids, with a front dinette that converts to a sleep torture device for the grownups -- exactly like the same trailer from Coachman, Forest River, and everyone else. RVTrader shows 5,717 available nationwide, ignoring all the other identical trailers from the other vendors.
If I'm so off-base, why didn't everyone who owned a Hummingbird dump them for a Jay Flight? There ought to be thousands of them out there, dirt cheap. But apparently, a whole bunch of satisfied owners are hoarding them, and nobody wants the replacement. If Jayco is so perfectly in-tune to their market, why haven't they noticed?
Here another example. At first blush, this one looks like the one: Winnebago Hike 100 H1316MB. Murphy bed, closet, wet bath, tiny fridge, and that's it. It's TOO small. And yet the silly thing has a 550' hitch weight! What are they thinking? Completely un-towable by an SUV. And yet there are half of many of them available as that bigger, lighter, bunkhouse Jayflight, with its 250lb hitch weight and front torture device.
I'm sorry. I don't see any evidence that the vendors have the slightest clue about this end of the market, at all.
