Picked up our Trialmaster two weeks ago and thought I'd update this thread with my thoughts. Overall I really, really like the Grenadier. It drives more like a truck than the new Defender (had a 2021 that I sold). At first it was slightly more involved with the different steering inputs but after 200ish miles I was used to it and it's a non issue. It's ever so slightly bigger than the Defender and the rear storage has better access. You sit more on top of the Grenadier vs tucked inside as on the Defender. Other than the view out the back with the split doors the visibility is better and I have fewer blind spots. May install an aftermarket rear view camera similar to the ClearSight one I had on the Defender at some point. It's not as high tech as the Defender, which I knew going in and shouldn't be a surprise to anyone. Road noise is similar, maybe a little less in the Grenadier (I had the expedition roof rack on our Defender, likely the same once I find a rack or roof bars I like). Stereo was much better in the Defender, which is to be expected going from the top end Meridian system to four speakers. I figured I could always upgrade the system in the Grenadier a bit if I want.
I read every Grenadier review out there and watched every video I could find. There are some people who've complained about the footwell bump for RHD drivers and some that have said it's not an issue. Doesn't bother me when I've ridden on the passenger side. Like most things out there on the various forums I visit, be it watches, guns, cars - the commentary is largely the same with similar personalities debating the pro's and con's. The people that like it will largely like it and those that don't (and many times wearn't buying it anyways) will find the negatives. Not saying the Grenadier is perfect and I was able to go in with eyes wide open since our counterparts in Europe have had the vehicle for around a year now.
In the end I'm happy with the move and I'd do it again. While I always liked the new Defender for what it was, the Grenadier is what I would have bought the first time had it been available. Just turned over 1,500 miles on the vehicle. To me it fits in with the GWagon Professional and the original Defender. If anyone has some experience with the previous GWagon (we have a G550) - feels almost the exactly same, just ever so slightly bigger. I'm just glad they brought it over to the US! Feel free to ask any questions and take care!
