That's an impressive track record. My 14 Vic Cross Roads was actually one of my "best" motorcycles (I've had many with almost 60 years of riding), and I compared it closely to the R18 when I was buying my Classic. While I am smitten with the R18 for many reasons the "old" and discontinued Victory offered more suspension, better seating, more petrol capacity and far easier maintenance, etc. I put approximately 45,000 miles on it in a year and a half and then decided I was going back to an Adv or Standard style bike. I was in line for the teased, bad ass Pike's Peak 156 based platform which was sadly delivered as another cruiser with the Octane-Scout. By the time they morphed that into the FTR I had moved on. Anyway, I was impressed with Polaris bankrolling two incredible engines back to back and how their poking at Harley resulted in major improvements for riders regardless their choice of Brands. Two of my riding friends were diehard HD riders and routinely went 1XX,XXX miles within 3-4 years before getting another. For a variety of reasons they were becoming unhappy with HD so in 2015 one was on Victory and the other on Indian and even with Covid restrictions the Vic is close to 120,000 and he will keep it while just adding a 2016 garage queen Vic as a primary long ride replacement. A clutch cable and starter motor were the only "failures" during those miles. The Indian is getting up there as well and I believe fork seals were the only "failures". Very high satisfaction and confidence in the bike especially when far from home is always a good thing.
I try to get something a little different every time I change bikes as there are so many great ones nowadays and while the R18 is amazing on many levels I would go for the Indian Challenger rather the R18 Bagger/Tourer options if for nothing else than ease of servicing on long rides. I do most of my own work and while all my previous BMWs needed little or no valve adjustments once settled in I hate the idea of hoping that I could skip an adjustment on a trip or face the down time and/or stupid $$ to have a shop do them while on the road and often that could be multiple times. It's not a deal breaker, but an annoyance just as their choice of tube required rims is. Anyway, you have a great stable and thanks for sharing your knowledge regardless the Brand.
