I just got Tamiyas "new" 1/48 Humvee and wanted to make it more up to date. I have already got Black Dogs Iraq war Humvee set, but is there anything else that I should get? I know that their offering in 1/35 needs new wheels, is it the same for the 1/48? Would like to do a early OIF vehicle

Thankful for help on the subject.
(and sorry for the repost but someone thought that it would give me more responses this way...)
