Thanks for the advice Debbie. I do appreciate it. The few 4x6 teardrops I've seen available online haven't had the height you describe. Perhaps I've been looking in the wrong places? I'd love to find a vintage trailer rather than build one but I've been scouring the internet every day for a couple of months now and since I want one by spring I figure I need to start building now if it's going to be ready to go next April.
I also went to the TCT West Coast Vintage Trailer Rally last weekend. There were 4 teardrops there, all were long and none had the kind of interior height I am looking for. I did however see a MInit which I'd never heard of before and fell in love with. If one were available right now I would snap it up in a heartbeat since it seems to be the only egg style trailer that weighs in well under 1000 lbs (my car's tow limit). You make a good point about the height slowing things down and taking more gas but I'm only pushing the overall height up by 6.5 inches over a 5' high teardrop which is a sacrifice I'm willing to make for the added comfort of being able to have more space when I'm in the trailer. I've even figured out a way to take an actual shower in the trailer by adding in that extra height! I guess my reasoning is I've read over and over how people get or build a starter trailer then have to get or build another one a year or two later. I only want to have to build a tiny trailer once.

I do still want a Minit thought. I'd love to have a tiny trailer for just me and the Minit for if I'm bringing a friend along or will be conducting interviews while on the road. The Minit would be perfect for interviews! If I never spot one I'll build a similar size or go for a Scamp or Boler someday when I've upgraded my tow vehicle.
Thanks for the encouragement Junkboy999. I'm really excited for the class. It's tonight! I've decided to practice with all of the tools and machinery I'll be learning to use at TechShop I'm going to build a half scale model as I go along. The 2'x3' trailer will give me some perspective of the build before I commit on the final and it'll make a perfect dog house for my pup which has the added bonus of being hilarious that he and I will have matching trailers

The Stubby is exactly what I want! But right now I'm trying to keep the trailer weight to around or under 700 lbs and it seems most wood trailers will push beyond that. Though I am exploring other materials to keep the weight down as low as possible if I do build something larger someday.
Thanks about the avatar. I did design it. I have 30+ illustrations I've done to mock the entire trailer out. I'll be posting them in a day or two and would really appreciate people here picking the design apart and sharing advice with me. Things I'm most concerned about are the weight balance and related weight issues.
