Some items work better in some models than others..This is what we have in our 3023
[Air conditioning - Yes, most camping happens in the summer and most places in the lower 48 get warm enough to need it (it IS a metal box in direct sunlight.....besides with DW's allergies we use it regularly
Awning - We like and use ours. We have lights to put out and during some parts of the day it is nice to keep the sun from shining through the big window the 3023 has on that side and baking the insides. We do not leave camp for any length of time with it up unless we have it staked down. Having one blow over the top of your TM and smack your A/C can ruin your day
TV antenna with power amplifier - Ours came with it, we use it, and it is a good resell value item.
TV shelf - We put in two corner shelfing units from shelf expressions and DW's small TV fits fine as well as a ceramic heater when it is cold out. (We use 2 heaters because the design of the TM doesn't make for good distribution of the heat from the main cabin back to the back bed area. For the "front room" you can find several do it yourself shelves including one I made. Adding a memory foam pad has made my original choice no longer useable. we also found that sitting with our backs against the forward bed and looking towards the kitchen the couches are much more comfortable than facing forward. We have come up with a new triangler design that will take up 3-4" of the self above the refridg, and hook to the TM wall using hanging cabinet mounting brackets, hold our 17" flat screen and the Direct TV reciever box. Pictures to follow once we build it.
Bike carrier receiver - We have one installed. Haven't used the bike rack in it yet but have used the wheeless trailer to haul blue tote and satelite attenna. Currently have a 6' tool box where I keep lightweight stuff. (ground mat, satelitte dish, hose, ardco cover etc.) see pictures at this link

Satellite dish - concur with CM211 - We like to camp in areas with trees. We went the route of stand alone antenna (DW found good deal on ebay) haven't tried it yet but we will eventually.
Solar panels (anyone know what size - and whether we should consider this??? Is this just for boondocking?) - Again, we prefer to camp in areas with trees so it doesn't work for us. We did put a second battery in to extend our legs a little when a/c is not available. We mostly camp with at least electric and water.
Electric tongue jack - Didn't have one originally but got one soon after switching to equalizer WDH. Numerous cycles up and down to attach/detach trailer, raise tongue and rear of vehicle up to put bars in place or remove bars soon made an electric tongue jack a very worthwhile investment
Microwave - We have a seperate Micro wave and toaster oven. DW is very accomplished cook and sometimes needs full size oven. (peach cobbler this last weekend was fantastic
)
Hanging Kitchen Cabinet Use it all the time. Not sure where we would put the stuff in it if we didn't have it but it would definately be tougher to get to. It does make the sink area a little dark and the installed light casts your shadow over the sink so we installed a single tube plug in florescent light under the cabinet that works great.
Swing-around tongue, reducing storage length two feet - our model will not fit in our garage so we don't have. Some folks have had problems with the induced stress this option has above and beyond normal solid tongue so if you need it to stow the TM in your garage go for it, if not avoid it as it is one more "complication" that you shouldn't add if you are not going to use it. THat said, it may be a good idea for resale value but I don't plan on selling ours any time soon and a search on the topic will show that the modification can be done afterwards if desired.
3 drawer dresser - Lovely idea and doubles as a TV stand but no place to put one in a 3023....
Stove cover - We have one and wouldn't be without it. It keeps so much stuff from falling into the stove burner pan. Even though we have modified the metal grate so the 4 legs are held in with cotter pins vice pressure washers it still is not the easiest thing to remove to clean the bib area. The cover looks good when closed (as well as providing another flat surface). We normally lay a towel across the top to provide pressure between the underside of the rear shell and the top of the cover to prevent it bouncing around.
+ Flooring - ours was a tech rep demo and came with the carpet and vinyl mix and we have been pleased with it so far (8 trips and counting). I can see where over time the carpet will show wear quicker than the vinyl. I guess we can always add a throw rug over the carpet as easily as over the vinyl.
Anyway as others have said each person has their own preference. These are ours. I hope they give you ideas and info to outfit your TM to your liking. After all, in the end it comes down to your preferences and happiness so go with your instincts.

One option not on the list is the 40 Gal potable water tank vice the 20. we have the 40 gal on our unit. It may not be on option on all models since I believe the 2720's have their tank under the sink. Ours is under one of the couches
