I have only owned pop ups and TTs, but I have buddy that has a 5th wheel. There are pros and cons to each.
The TT works best for us as I enjoy the room in the back of my Silverado to haul firewood, grill, bikes, and our cornhole boards. With a 5th wheel I would greatly miss this room. Also with a 5th wheel you have to have a truck capable of towing it. Unless it is a smaller 5th wheel you would need atleast a 2500/250.
As far as room goes, the trailer industry has come a long ways and most campers have tons of stowage anymore. Although a 5th wheel does have huge storage under the beds, TTs have mostly gone with pass through storage here as well. Door ways just arent as big.
There are tons of possibilities with any camper. Outside kitchens, huge slides, etc. etc. etc.
5th wheels tend to be heavier, which will kill your gas mileage. Most companies have now started their lightweight lines that are as big as the standard campers, but weigh considerably less. We just purchased a 2011 Jayco Jayswift 264BH. It is a 29' with bunks in the back, queen in the front and no slides. (didnt want slides). It only weighs 4550 unloaded and my 2500HD tows it easily.
The Jayco jayflight 26BH is the same camper, only it is not the light series and it weighs in at 4725. Not much heavier, only close to 200lbs.
You will just have to look at what size of camper you really need, can you afford the camper, can you afford the tow vehicle, and most importantly, can you afford the gas with the larger campers! Insurance is relatively decent, I only pay around $180 a year, and the difference between my '07 and the '11 was $1!!
As far as all of the add ons you can get just look at them from a neutral stand point. Such as the exterior kitchen. Would you use it enough to justify the added cost? How many people go camping with you and will be staying in the camper? Do you need slides? Do you need bunks? Do you need the upgrade frig and oven?? All the extra items you stick on the camper jack the price up considerably!! Before you know it, you will have a camper with a sticker price of well into the $25-30K range!
The best thing to do is wait until the 2012 models come out and take a look at the leftover 2011's. The warranty is the still the same, as long as it is a new model. And this is why I went with the Jayco, they have a 2 year bumper to bumper warranty, where the other manufacturers only carry a 1 year! Sometimes that extra year is worth it, and they are very comparative to any other manufacturers prices!!

I, too, have thought about tt and 5th wheelers. Haven't decided to jump, yet, but am leaning toward 5th wheeler. Travel trailers seem to be more difficult to tow and that worries me a little.
I have the standard load dist hitch and an anti-sway control on my truck, and my 29' jayco tows great! Backing a 5th wheel is probably easier, as you have more turn radius with it vs. a TT. But I havent found any campground where I cannot get into. Even with my non-direction giving wife!!! LOL (Ok ladies, flame on!!)
