Here's what I'm talking about. The first picture is a brand new, $14K Coachman Clipper 14CR. Because you just can't have enough 3" cushions. Of course, it has the standard, requisite dinette up front, which converts to a miniature 48x68 inch, bed-like collection of 3" sofa cushions, for your night-time discomfort. On the side opposite the galley, it has that all-important bar, with a couple of really uncomfortable fold-up bar stools to sit on, just in case you forgot to convert your front nighttime sleep torture device into your daytime luncheon torture device.
But don't think I'm just picking on Coachman. I count 21 other nearly identical versions of this trailer, from every imaginable competitor. You can spend over $40,000 on this misery, if you're determined to get the best!
And you still need a pickup truck to tow it, and a storage lot to keep it, for the other 11 months of the year. On the bright side, you do get a dry bath and a decent-sized freezer, with a stove for all those gourmet dinners you'll be cooking, out there in camp wilderness. You even get a closet for your tee-shirts (provided you don't mind smashing them down a little, because it's too narrow for a standard-sized hangar). And, to top it all off, it even comes with that all-important 8' ceiling!
The 2nd picture is how I would redraw that floor plan. Instead of a dinette trying to pass for a midget's bed, mine has a real full-size bed that uses a real mattress, in a size you can buy anywhere. As a bonus, I get an enormous pass-through trunk underneath. But I had to give up the gourmet dinners (and the heavy propane tank) to get it. Instead of that silly bar, I have a double-recliner. It would have swiveling TV trays with drink holders, attached to the arms. Yes, it would have to be specially made to avoid the wheel well, but notice, there is plenty of room to fully recline while watching TV. Oh, and I fixed the closet, which merely required moving the door 6" to the right.
What you can't see is the 6' ceiling, which allows the unit to fit into a standard garage, while reducing the weight and air resistance, so that an SUV can tow it.
See how easy this is? Why are 21 different RV builders unable to figure this out?
