condensation collecting inside the roof

[Silverstreak]

When I first got this cart last year, I could hear water sloshing around in the roof, and it would drip down on me through the holes. I drilled several more small holes in the back and caulked around the bolts on top. It worked for awhile, but the other day I was driving it and drip, drip, drip down the back of me. It hasn't been out in the rain hardly ever. Anyone have a better solution for that?
Thanks.

Drill holes in the under side corners and park it on a slope.

Is it "normal" to get water in there? I did drill some holes in those areas. I guess I just have to park it on a slope more often.

I had to drill holes in mine to drain it as well. I found out the top bolts were cranked down tight enough to crack the plastic a bit letting water in. I just put a few pieces of black duct tape over the area where the bolt is to keep water completely away from there.
