I have had problems with wear on front tires since we bought our Prism three years ago. I can find no one that can align the front end with the modern alignment equipment. I even took it to Freightliner after I exhausted trying to get it aligned by Mercedes. The reason I am being told is that they cannot get a shot (beam) from the rear tires to the front because the Prism box blocks the beam for alignment. Has anyone else had this problem and can anyone offer advice. It is no fun driving the RV when you know it is not correctly aligned on the front end. That is about the only problem I have had but it is a real nuisance. Also can you tell me what tires you would recommend buying. It came with four season Continental tires that i have been told are not too good and cause a bit of a rough ride. Thank you - Mike Wagoner (832) 274-6542
