So I've been trying to buy a van for a 6+ month road trip next year and came across a 1983 Mirage camper. It runs and appears to be in decent shape, but it has the 5 lug rear axle. Were these axles okay in the mirage since they're on the smaller side, or would I be taking a massive risk not replacing it? And speaking of replacing it, if I could find a solid replacement axle, is it something that someone with very little mechanical experience could do if they had access to an automotive garage + lift?...If not, about how much would I expect to pay for the replacement? I really love the look and style of this, but im not sure if it's worth the trouble now...They're asking $5,500 for it which seems like a steal.
