hey guys i have been looking at a few different slider options for my 2012 tacoma dbl cab short bed i wouldn't mind spending 500$ but than i remember i have to pay shipping so i am looking for a pair of sliders for around $500 shipped. i am not doing anything serious so i think the h.r.e.w tubing would be fine. i am also looking for bolt on! anyone have any experience in these? http://4xinnovations.com/p-RS04.html or do you guys have any recommendations?
