Conversion of my Blair Cargo trailer

I've been hanging around here off & on for a few months now trying to decide on a traditional teardrop or cargo trailer conversion for my freqent bicycle and kayak treks. I think I've decided that I will start with a trailer conversion as I already own a cargo trailer that I have many years & many miles experience pulling all over the country.
My trailer is a 1992 Blair Cargo Trailer. I used it pretty hard from 1992 to 2000. Sporadically since. It has some wear and tear but has been reliable and a good trailer. I've probably put 30K or more miles on it since 1992. It's been coast-to-coast 5-6 times and just about everywhere in between hauling Boy Scout gear/equipment and moving my kids around. I have also spent many a night sleeping in it when a severe rain storm wash out my tent!
It is 5'Wx10'Lx5'8"H. Basically it is now a box with a 45"Wx60"H rear door. Walls are 5/8 or 3/4 inch fiberglass laminate over plywood. Chassis is a heavy duty horse trailer frame with a single axle. Weight is approx 900 pound with 2500 pound payload capacity. Wheels are 225/75R15. Roof is single piece translucent molded fiberglass with 1x1 steel tube support framing.
I've been looking at everyone's conversion pictures on this site. Thanks for posting them. I will eventually get around to taking some photos and posting. Right now I have to do a major clean up and small repairs of some water damage before beginning my conversion. I will be replacing all or part of the floor, recaulking all seams and repairing the bottom 6 inches of my door (water damage). Not sure the best way to go about this since the damage to the door is in between the fiberglass laminate where the plywood core has the water damage. The fiberglass is still in good shape but the plywood is crumbling. Possibly I could install some kind of "kick plate" which will strengthen the door bottom and prevent further weakening. I also have to install a slide bolt lock inside so that I can lock it from the inside and I also need to figure out some way to prevent it from being locked from the outside while I'm in it!!
Right now, I'm trying to decide how many windows to install, what type of windows, positions, etc? Should I insulate it? Should I put a roof vent or two in it? Would a roof vent weaken the fiberglass or should I just vent it with side windows or a front or rear window? Possibly I could install an exhaust fan/vent through the 6 inch wide door frame over the door?
Once these issues are sorted out I would like to decide on a floor plan. I would however, like any fixtures inside to be easily removed as I would like the option of using it as a cargo trailer occasionally.
Anyone here have any sources for windows? Pros/cons of different types? Sizes? Costs?
I plan to eventually build a sofa frame that converts to a bed with storage underneath. Also, some cabinets, closet, counter/table top, minimal electrical wiring & lighting, etc. and storage cabinet for a porta potty.
I don't have a big need of a galley. Maybe a small counter top, small sink/basin, and possibly a set up for a small microwave. I don't plan on doing dedicated camping in it. Just sleeping and changing quarters for my biking/hiking/kayaking treks and travel to and from. I have a really nice Coleman/Fleetwood pop up camper for dedicated camping trips with the family.
Anyone know of floor plans for such a small footprint? I've been searching the web but have not found much.
I will post progress as it happens. And, I'm open to any suggestions or leads on ideas.
Thanks,
