Here is what I decided on, had built, and just picked up last Saturday morning.
26 ft, 15K, bumper pull built by Kaufman Trailers in Lexington, NC. I looked and studied a lot of different configurations and setups and with the help of Yeller (big thanks) pulled the trigger on this about 5 weeks ago. My truck is setup for gooseneck but I wanted to keep the weight down as much as I could and still be able to lock things up in the bed of the truck. I haven't gone down the road with both of them loaded yet but so far I couldn't be more pleased. It is very well built. The trip back to Ohio Saturday was 450 miles empty, part of it through those hills between I-81 and Charleston along I-77. Unless we were hitting 80+ mph it beat us to death empty, but was expected as it's longer, heavier, and stiffer suspension. I had been a little concerned about getting into my driveway where I keep my 73 (green). Gated community and you are not allowed to leave anything parked on the street, and you are not supposed to have trailers in the driveway overnight but I do occasionally and nobody ever says anything. I was actually able to back it in easier than the 16 ft trailer I had, the position of the axles combined with the extra ground clearance let it clear going up at the angle I needed. The 16 ft would scrape if it wasn't positioned perfectly. I loaded the 73 and pulled it 20 miles yesterday to my Daughters house where my other Bronco is kept. It wasn't a very noticeable difference pulling 1, no doubt with 2 will be considerably different but I feel like it will pull very well.
With both loaded there is enough room to adjust a little bit and still keep the bumpers apart. I was short on straps plus it was a rainy day yesterday, smarter to wait until a dry day to test run fully loaded, should be able to get them both out and test within the next couple weeks. Here's a few pics.
Sadly, there are 4 trailer places local to where I'm at in Ohio, not a single one would work with me to build what I wanted. They were only interested in selling cookie cutter trailer they built or had on the lot. Kaufman Trailers worked with me right from the get go, and saved me $2500+ of what I would have paid locally for something not exactly what I wanted. I will update this later on to verify I'm still as happy as I am now, but for now, I highly recommend them.
