inner dimensions

Hello,

I am a new member to this forum. I am presently planning to build a trailer. Three
things that a longstanding search through the world of vintage trailers has made clear.

Many are nearly completely torn down and rebuilt to a degree that comes close to starting from scratch.

It is nearly impossible to find one that isn't limited in the available interior height or bed length. I am 6' 5" and done with crouching over or sleeping crosswise to be inside a trailer. But, I am open to finding some option that might still yield a possible vintage candidate. 

And finally, I have a preference for designs that predate canned-ham styles. Most notably designs with clerestory roof lines running the length of the trailer. Among other things, that appeals to my height challenged experience with the typical trailer. But that is not a make-or-break issue.

Equipment and skill sets are not an issue. Viable space to do the work remains a challenge since all available space in my recently downsized studio is dedicated to other uses. So while I enjoy perusing the restoration labors and techniques on this site, I thought I might appeal to the greater knowledge of forum members for any awareness of designs that exceed 77" of head room.

Thanks for taking the time to read and possibly respond to this.
Kurt
