Im selling off my OMS IQ BDC and i think i might get the ranger LTD. I see the 2008 is selling for about 500 and the 2009 is selling for about 770 but the only difference the store can tell me is a shoulder strap change and an extra dump valve, is that all u get for 270$?? are there more significant chabges? is it worth spending the extra money fr the 2009?
