I have a pretty deep drop floor/foot well in mine and would not go camping without it. Forget the inside table. I have found that I often set out high winds inside along with rain and snow and cold. And I don't like setting up and taring down a shelter tent, which often causes problems in the wind. With a deep foot well you need to build the trailer higher than normal. Or like my next one have the sides higher than 4 feet. Will had some complexity but it is for this fat old geezer. Also in the bottom of the foot well I added a trap door so now I can stand inside.

You can just see my feet under the trailer. In front of my feet is a step stool I built that I use a lot and not just to get in and out of the trailer. As this was my first trailer and also the first teardrop I ever saw up close my foot well is a bit to small. Also remember that the distance from the front edge of a kitchen chair to floor is 17 inches. If you make your foot well so it goes to the rear a ways you can get by with a lower chair hight so your feet can go out. Meassure your car seat and foot area. If you have a big luxury car find some smaller ones to measure. Mid size and compact. See what you can stand for a few hours.
