Here's a few pics of a couple that were at our Wrench & Roast at my place a couple months ago. Not the best pics, but the quickest I could locate.
The silver one is BroncoLoupy on here. It is a 36' or 38' Continental Cargo that he speced and it has full front living quarters.
The white one is a Featherlight owned by Chris Hockett who hauled it all the way from Seattle to my place in PA for the weekend. It is also in the 36'-38' range as I recall and it too has full living quarters. This is a tandem axle, but has heavier axles from what I remember (8K each?)
The red trailer is ours that I had at one time thought of installing a mini-living quarters in. It's a 40' Southwest Expressline with an extra 18" height. We wanted to be able to haul 2 EB's, so there is no way to do that with a full living quarters layout unless it was a 52' (maybe a compact full layout in a 48'). I was going to just do a front corner shower/toilet and maybe a fridge, micro and cooktop on the opposite front corner with some wall cabinets for storage and the bed up on the upper bunk over the hitch. With only 32' of lower deck, that would put the bumper of the front EB right up into the shower and would be even more of a PITA to tie down, so we did not go forward with it. It it was a 44' I would have.
Most Toy Haulers are built too light for EB's, either in axles, or in the strength of the rear door, so be sure you check the specs closely.
One thing I really like about Lou's is that he did not get a beavertail, so his has more rear clearance which is nice going in and out of many of the places we go. He never drages the rear corners like I do with the red one. It makes the ramp steeper, but with 4x4's, who cares?
