My wife really digs those camper vans like the one you posted. The Mercedes is a pricy little thing though, go figure.
My Dad recently bought a Colorado, should be fine to pull the 24' pontoon, but I think he wants to break it in for a couple of years while I tow it with my 6.2 GMC. Which, I continue to be fortunate with--saw yet another blurb about engine failure for the '21-24 models, and the replacement engine ALSO failing. Seems like 2020 could have been the sweet spot.
Japanese stuff running longer has to be the reason for them keeping their value better than domestic for the past 40+ years. Maybe Detroit has their act together, but even if they did, it will take decades to even that playing field. GM's engine problems can't be helping that cause.
