Well you still have the OEM UCP on there, so it looks like it wont interfere. Is your exhaust stock forward of the muffler? So, single in, and dual out?
As for the gas tank, I have not really looked at it much. I'll have to take a look and see what there is to attach to and see if I could come up with something.
The fender tray pic you sent is the same as the one in my truck, so it will work in yours.
Are those tips easy to remove? I know I've been in plenty of spots where those would get crushed sticking out under the bumper like that.
