I bought my DJ last month and I'm getting it ready for my trip to Texas. I will be installing the Curt hitch and I have just a few questions. First will I need to have the re-flash after installing the wire harness? Second, what am I going to be able to handle weight wise with the '09 R/T? The trailer I'm looking at getting weighs 845 lbs empty, if I have a bike break down most that run with my group are around 900 lbs, that's gonna be a combined weight of 1745, am I gonna be able to handle that? Any help would be greatly appreciated. Thanks all.
