I like that rentec rack and trunk! You need bigger side bags.... shoot, you still got room till you hit your exhausts.... Need some massive GIVI or other hard luggage!
That tail trunk sure does look functional! I would want a bigger one though - gotta have one that fits lots of groceries, or camera gear / hiking clothes, then you can swap out the aerostich for the gear, lock everything up nice.
I keep thinking about a rack for mine, but the leatherlyke side bags need the triumph rail for their mounting brackets.... I suppose I might be able to drill a rentec rack.... that would be an expensive experiment if it went wrong!
Instead of a tail trunk - I use a seat like the king and queen seat - keeps a soft bag in place, and, if you have a bag that sits over the sides of the seat very far - you can always modify a plastic cutting board, secure it in place with some straps, and use the soft bag on top. Or, put a thinner cut down plastic cutting board in the bottom of your soft bag to hold up anything inside. Not waterproof or secure like a rear tail trunk. I'll probably head that route if I start touring more on the bonneville (got an older tiger for that now - it has crappy, yet functional, hard luggage).
awesome setup bro!
