Alright, I found a set of lights for $12 on summit racing.
Without any cargo, the whole thing shouldn't weigh much more than 100 lbs, I hope. Yah, loading it up with luggage might affect handling, but that just means driving more slowly. If I ever fit it up w/ water tanks or similar for travel, I can put those up front to help the weight distribution.
Looks like the max tongue weight for trailering is only ~350 lbs, so making a bumper rack for my motorbike might be out of the question with the bumper as far out as it is now.
For simplicity, I'm pretty much settled on the straight back sides now. I'd have to change too much to accommodate just a 3" taper on each side... meh.
