Hi, neighbor!
We're in a similar boat to you, currently have a TT toyhauler, and want to upgrade to a 5th wheel in the next year or two, in the 50-60k range. When we were looking at Toy Haulers and inquired about Grand Design's Momentum line, the salesman explained that Grand Design are considered a "luxury" brand, and more geared towards full timers (although I know not all GD owners are full timers). When walking through them, they felt nicer than the Keystone units we were looking at, had nicer finishes, etc. So that would explain the pricing. I know we weren't that interested in the fancy stuff, so the Keystones were just fine.
Just an fyi, we've visited the Windish dealerships 3 times already, and really like them, and we will probably purchase our next one from them. Not pushy, and the salespeople seem to be pretty knowledgeable. We've been to Wheat Ridge twice and Longmont once. We bought our current TT toy hauler at Discount RV in Longmont, which is now LazyDays, and I wouldn't buy from them again, although their service department isn't bad.
