We have the A.F. 29 5T 5'vr which is 33-34 ft. length and have been able to park it about anywhere--pull thru, back in, etc. with the exception of U.S. state or county parks. Most park campgrounds assign a site--but, you do have the option of parking your rig by the office(entrance) and walking out to the site and see if you can actually fit length or width(slides)and height(trees) in that site. The other problem is when you get the 5'vr parked--than is there enough room to park your truck. State and County campgrounds or generally older and don't have the width for slides. We have traveled all over the U.S. including Alaska and through British Columbia to the Yukon Terr. and very seldom have trouble getting a site. But, we always call in advance to reserve the site. We are members of K.O.A. and Good Sam and that helps a lot in getting a site that fits your rig. Lars
