I only have 3500 miles on my ‘21 elevation 3.0, but I love it. For road trips it’s amazing. It’s also great around town, very punchy and moves around well. My trailer I pull is only 2000 lbs, so obviously I don’t even know it’s there. Maintenance doesn’t seem any higher than my gas vehicles, but it does use DEF and diesel fuel seems to cost more. I feel like the fuel mileage easily compensated for the extra cost of fuel, and if you buy the DEF at Wally World it’s pretty cheap. I’m at ~$15 of DEF on my 3500 miles.
