In terms of half-ton towing, I tow with a 2013 F-150 King Ranch Ecoboost. It tows like a dream and is very very stable which I attribute to the distance between the wheels. My previous trailer was about 1-2k heavier and towed just as well except would have more sway in high wind.
The awning is large enough where there's still usable area under the slide and in front of the awning. The slide isn't terribly deep. What bothers me more is the fact that the LED lights go all the way across for no apparent reason. At night, because the slide is hiding the lights, you basically have a dark area. I'm sure it lights up the top of the slide real well, though?
For my family we have plenty of storage inside -- there are still unused shelves in the pantry area. In the bedroom, we haven't had any issue with storage except that the under-bed storage is useless. There are no air/gas struts to hold up the compartment, which means you have to try and balance it on your head to get under there. The cabinets and "wardrobes" are nothing special -- pretty typical of what I've seen in others with a similar floorplan. We were also shopping Rockwood's, which had a slide in the bedroom and allowed for a much bigger wardrobe.
The bathroom storage is lacking. There's a medicine cabinet and under-sink cabinet. We keep our towels in the large coat closet as you walk into the door. There's enough unused space above the toilet however that we plan on adding shelves.
The slide operation is nothing special. They work well and are more quiet than in my previous TT. The biggest concern I have is a failure of the slide. The manual operation would consist of using a cordless screwgun and attaching two flexible bits they provide. The motor is above the slide inside the coach, so you'll have to (somehow) get up there and operate it while not getting in the way of the slide and still reaching the back. It's probably better explained with a picture, which I'm happy to take if interested.
Overall, we've only found a few things that we're unhappy about that are fairly easily fixed. The lack of outdoor space was fixed by organizing better using small totes. The 30A power plug mouse door is inbetween the grill and spare tire which made it very awkward to operate -- I upgraded to the Furrion cordless system and that problem is solved. I wanted the magnetic latches on baggage doors from the higher-end models -- that was fixed with a $10 purchase from Amazon.
We've been very very happy with our purchase.
I hope this helps in your decision. Again, if you have any other questions or want pictures let me know.
