Congrats on your new camper! BTW, what do you pull your Travellite with and what kind of MPG do you get? Yes, an Aliner is a specialty camper that is not right for most people. On the bright side, I'm sure someone will now get a good deal on a slightly used Aliner - like we did.:)
We customized ours extensively to make it suit our needs. Most Aliner owners do. We rarely use our dinette, and couch. Instead, we leave it made into a king bed which gives us very little room to move around inside, but with just the 2 of us camping we're fine with the intimacy. But frankly, what other full-featured (king bed, shower/cassette toilet, fridge/freezer, microware stove, air conditioner, etc.) hard sided camper can you pull with a 4 cyl car and get 22-25mpg towing, and still have a 30+ mpg vehicle to tour the area when unhooked? Of course if you don't travel much and can afford a big dedicated fuel hungry TV then this may not be important. For us, the great gas mileage is less important than the expense of buying, insuring, maintaining, etc. a dedicated TV. We now have over 230,000 miles on our little Chevy Cobalt (about 30k miles towing) and it still runs great, towing our 1,700lb (loaded) Aliner up and down the steepest grades at the legal speed limit (up to 75mph across Texas 2 weeks ago).
We easily live with the cramped space inside. This forces us to spend more time outside when we camp. If you like to stay inside a lot, then you would probably go stir crazy in one. If we're just over-nighting, we often don't unhook, (perfect for those 700+ mile days) like we did a couple week ago at a visitor's center, like this.
If we plan on staying a while then out comes the screen room, awning and all the goodies, like this:
Different strokes for different folks. I hope your new camper suits your needs as well as our Aliner suits ours.
