for you guys that want to keep the liner, all you really have to do is pull the liner about 2inches back where needed. its only going to be a bit of a pain if you remove the extra lip as it makes it alot harder to see what your doing. but you can do it if your careful. the main reason i removed it is because i plan to troop with it every nw & then and its ALOT cooler (temp wise) with out the padded black liner in there. and enables me to stick a fan up in there if i so choose.
