I recently compared The Allegro 2014 32CA to a Newmar. The Tiffin is on a 22,000 GVWR chassis, the Newmar on a 20,500 chassis. If the heavier chassis is a little larger web on the I beam this could make a little difference. The Tiffin is a 22.5 tire, the Newmar is a 19.5 as I recall. There is a little more difference. The Tiffin has an interior height of 83.5", the Newmar 80", a 3.5" difference here. Finally, the specs show Tiffin at overall height of 12'10", Newmar 12' 4". Yep, the Tiffin is higher. Hope this helps.
