Hello I read your question and I can tell you what I have, 2005 Dodge 2500 heavy duty 4x4 5.9 D on top I bought a used Northern Lite 10.2 that rebuilt due to water damage of some sort. the over hanging part, (rear part) structural damage, if anyone is interested look up the rebuilt in YOUTUBE under Hello campers, but any way it is a little top heavy and rocks a little due to single rear wheel, nice camper. But that particular model and year 2004 rear end was not structural sound in that year, After complete tear down it is now ok. maybe the new ones are built structural better. But I would check out this problem before you spend such large amount,
