I put two 250's (a YZ and a CR, both 2-strokes) with gear and firewood in mine on a regular basis and she does just fine (although, as I said earlier it's pretty low in the back). My truck is supercharged, so I don't notice too much lack of power even with all that weight. One time I somehow fit in the two 250's AND a CR 80 (facing backwards <img src="/forums/images/graemlins/smile.gif" alt="" />)! No complaints here.
