I have a 2000 Bonanza 2 horse stock combo similar to this one:

I'd like to add plexiglas to the slats to keep rain out this winter. As you can see from the picture, there are structural object in the way, so I can't just screw it up there. Any suggestion on how to add plexiglas to a trailer like this? I could put it up permanent on the butt side, but I'd like to be able to take it down on the head side for the summer. Do you have to pre-drill holes in plexiglas? Do you need a special drill bit?

Thx.

I had a Cornpro stock/combo trailer with similar slats. I enclosed both sides using individual Lexan panels screwed to the horizontal slats, between the vertical studs.

When you drill acrylic, use a slow speed drill, and drill holes that are two fractional sizes larger than the hardware you plan to use. I used stainless oval head bolts and hardware with self locking nuts, and trim washers against the Lexan. Do not over tighten the bolts, just add enough tension to take the slack out of the hardware; the reason for the self locking nuts instead of lock washers which have to be crushed to work. If the panels are distorted with overtighened hardware, they will crack and fail.

Acrylic is much less expensive than Lexan and will work well. I would only use a thickness of 1/4" or greater. It can be cut with common woodworking tools, a table saw is a great help but not mandatory.

A trip to Home Depot resulted in buying the heavy duty screen material that you put on your windows to reduce the heat from the sun, screen door framing and the little flip levers that you use to hold screens in place. I plan on building a frame that I can slide in on the inside of the trailer, and using the flip levers to hold it in place.  The mesh on this screen material is very tight and should keep most of the rain out and block the wind, while allowing air flow.  I'll post some pictures when I'm done.  Thanks for the ideas.
