Havent owned a Aliner but i did own a Chalet Alpine "Trail Boss" edition (Dexter axle, factory lift, etc). That said, i would take it down dirt roads, etc but probably not much more than that. I think the suspension could take it, but the drawers would probably rattle open if not really loosen things up. I think neither of the trailers were meant to be "offroad" much..Atleast in the sense of "offroad" where i plan to take the Chaser i bought after i sold the Alpine! If you really want to wheel with your trailer...I personally would go a different route. As others have stated, the width alone would limit where you can go.
