Well, the Wagoneer is based on the RAM 1500, and we have a fleet of RAM 1500's with most having over 200,000 miles on them at work. Only mechanical issue has been the exhaust manifold studs, which will be a bit more of a task for you when yours go. Depending on the year (I haven't looked yours up) there may be a stainless header option, but some also have integrated catalysts, which may eliminate that option.2017 4Runner TRD Pro. 175K miles. Vehicle has been flawless with no mechanical issues whatsoever. Good luck getting that out of the new Wagoneer.
Now that we have that out of the way, do you have anything useful to add to the conversation?
