Ditch the AC idea and the slide-out idea if you're towing with an Odyssey. It'll be really heavy and pushing the safe limits with those options. We are a family of 4 and I'm 6'4" while wearing shoes (which we do a lot inside the PUP). In our Jayco 1007, I have PLENTY of headroom. Sleeping on the 'king' is no problem, as I don't sleep fully extended. Knees or waist are always bent a bit. Unless your husband sleeps like Dracula in a coffin, I'm sure he'll be fine with a PUP King bed. Having said that, I'd recommend a mid-2000'2 Jayco 1007. It tows easily behind the Odyssey, it has everything you want (minus the AC and slide out as I mentioned earlier, you aren't getting if you're not changing TV and also definitely not for under $3000!!). You can get a porta-potty from any camping store or even Walmart and store it in the trailer. Your husband will fit. Maybe not through the door but at 6'6" tall I'm sure, like me, he's used to ducking through EVERY door he goes through. In the Jayco 1007, we removed the base and table for the U-shaped dinette and use it only as seating. That way, getting in/out of the king bed is simple. The kids (7 & 10) get the rear double bed and/or the other bed near the rear where the main dining table drops to create a large twin / small double. The kids don't mind (and quite enjoy) climbing over that to get into the rear bed anyhow. Word of warning, the Jayco 1006 is heavier due to the storage compartment and other things. I much prefer the layout of the 1007 to the 1006 anyhow. Both, however, should be available at your sub-$3K pricepoint.
