There is a solution to the bickering. Instead of being concerned what others decide, discuss how you use your TC and why your preferred configuration works for you.
Maybe I should just give an example. I am a photographer and enjoy exploring scenic areas. I tend to travel a lot. I also live on the East coast and like to visit in the Western States so that adds to the travel. When it comes to the compromises on size, weight, convenience, I have decided to keep the weight down as much as possible. I also like being able to hit a rest stop and use my RV toilet, kitchen and often take a nap. I don't want to take the time to deal with a slide or need to find an oversized parking area. I also do some stealth camping and want to be as inconspicuous as possible.
If you use your TC to be able to tow a boat and stay at a nearby lake for a week or two, I can understand why you might want to maximize comfort and a larger TC with multiple slides might fit your needs.
