OTHER STUFF
Bumper storage tube.  A length of 4" corrugated drain pipe makes a lightweight storage tube that rests on the stabilizer screws and is bungeed to the stabilizers.  The bungees serve double duty, also keeping the stabilizers from drooping during travel (which they have been known to do).  The ends of the tube are capped with slotted drain covers (one cover is screwed on, the other is removable, secured with a cord).  In it are stored all my sewer connections.
"Attic" shelf.  A wire shelf hung from the center pole is a great help for storage, especially for shoes, since there is so little floor space.  For maximum length, I had to get the shelf as low as possible, and because of the tight space between the A sides when folded, there wasn't room for any kind of wall-mounted shelf bracket.  Hardware on the sides of the A-wall extrusions would not get in the way of anything.  To provide  the most stable support for the downward stress of the shelf, I used 2 hooks from the back of suction cups.  A screw and fender washer fasten each hook to the narrow edges of the A-wall.   I crimped small S-hooks on each rear corner of the shelf (the 1" lip of the shelf goes up, against the wall), where they can catch in the A-wall hooks.  These S-hooks stay attached to the shelf.  At the center front of the shelf (no lip), I crimped the end of a lightweight chain. Around the overhead pole, I put a large plastic cable holder, fastening the ends together with another crimped S-hook. 

To hang the shelf, I slip the shelf S-hooks over the hooks on the wall, then hook the shelf chain on the pole S-hook.  To keep dirt from falling through the shelf, I top it with a piece of plastic carpet protector.  During travel, the shelf stands on the floor against the bed. 
Desk supplies.  The raised potty platform gave me about 2" of storage space underneath - not enough for shoes, as I'd hoped, but just right for two 6"x15" drawer organizing bins.  One bin holds office supplies like pen, pencil, scissors, tape measure, staper, sewing kit, notepads, etc.  The other is my "medicine cabinet" with pain reliever, alcohol, tweezers, dental floss, bandaids, tums, etc.
Dishes.  The counter space to the right of the sink was just big enough to accommodate a clear plastic wall-hung office organizer that holds my dishes, silverware, coasters, small frypan, cooking utensils, hotpads, dish detergent.  Wall files, drawer organizers .... who'd have thought that an office supply store would yield so many camper storage solutions!
Kitchen cupboard.  This little toilet-top bathroom organizer is a perfect kitchen cabinet.  We had an identical one in our canvas pop-up, and it's now at home in our Aliner Classic.  I despaired of ever finding another like it, until we emptied the apartment of a deceased aunt.  She had two in her bathroom!  The handles are good for drying dishcloths, the top makes a good shelf, and inside I store my mug, drinking glasses, bowls, condiments, can opener, and the like.  It's also easy to move outside to a picnic table.
Food.  All of my foodstuffs are in a plastic tub that fits nicely under the lid next to the potty.  In front of the tub, there's room to stand rolls of plastic wrap, aluminum foil, and baggies.
Garbage.  For wet, kitchen garbage, I use a plastic paint bucket with a locking lid.  I line it with plastic grocery bags which are easy to put out for trash.
Paper towel holder.  I adapted a cheap economical chrome paper-towel holder to hang from the wire shelf by putting large locking cup hooks through the screw holes and into plastic wall plugs to hold them in place.  With metal snips, I cut off the excess screw threads and plastic.  Hanging the holder is a simple matter of shoving the cup hooks onto the shelf.  The locking tabs hold it in place.
Shower supplies.  In a zipper lingerie bag (Dollar Tree), I keep shower gel, shampoo, conditioner, razor and nylon puff.  A shoelace threaded through the bag lets me hang it in a campground shower.  In the camper, I store the bag in a wire basket hanging from my shelf, and everything dries quickly.
Clothing.  I keep my clothes in two canvas tubs behind the bed-cabinet sliding doors.  They have handles and are easy to pull out.
Setup tub.  I keep small setup stuff in a small Rubbermaid Toughneck tub which fits in the upside-down step stool for travel.  It holds things like electrical adapters, polarity checker, "J" trap for sewer line, teflon tape, duct tape, headlamp, "Y" and pressure reducer for campground spigot, tent stakes, and flowerbox.  At the campground, I slide the tub under the camper.  On the lid of the tub, I keep the outside sensor for my in-out thermometer/clock.  Under the camper, I also stow a rectangular bucket with picnic tablecloth and clips, utility brush, and shower curtain (to cover table at night and keep off dew and birds). 
Water filter.  To keep the water filter from leaking when stored in the front storage compartment, I found that I can set it upright in an empty plastic wipes container.
Tubs and baskets.  For a small camper, the under-bench areas provide a lot of storage.  I've found tubs and baskets that fit well in most areas.  Under the foot of the bed, a canvas basket holds extra toilet paper and paper towel, paper cups and plates, extra towels and a small rice cooker.  Next to it is a plastic shoebox for small items (fuses, mantles, clothespins, bulbs).  Behind the battery box, a long narrow bin holds a small tower fan and laundry detergent.  On top of the battery box is my bedding.  Behind my clothing baskets is another long narrow bin with three 1# propane bottles and a DVD player.  Forward of the clothing baskets are a hanging folding clothes dryer and three more tubs for shoes, jackets, and bulky items.  One of those tubs has a lid on which is velcroed a plastic basket with my clock, radio, extra flashlight, bird guide and binocular.  Food is all in the tub next to the potty.  My towel is stuffed on one side of the food tub, and a writing clipboard stands alongside it.  On the other side of the potty are bags of toilet chemical and a brush/dustpan.  In the bench next to the sink are a 5# propane tank, electric heater, bedside lamp, chandelier, electric burner, electric kettle, small propane lantern, 1-burner propane stove, and nesting cooking pots.  On the back of the door is a bag with toothbrush and toothpaste, sunscreen, insect repellent.  Have I forgotten anything???

Note:  Cheap padded lunch bags are available in many different shapes and sizes and I use them to protect the DVD player, the lantern, the stove, and the electric burner.
Front storage compartment.  We don't have a front storage compartment on our Classic, but I'm delighted and amazed at what it holds in the Alite.  In it are a fire extinguisher, water filter, grease and grease gun, water hose, utility sprayer, detachable power cord, extension cord, large and small folding tables, camp chair, stabilizer crank, chocks, kneeling pad, collapsible fresh water jug, collapsible grey water bucket, rubber mallet, clothesline pipes, and Neat Sheet (outside rug).  And there's still room for more!
