Congrats on the coming retirement. I do not have any specific knowledge of the Monarch. However, our Monaco Coach is well built and Monaco has provided good customer service to us.
I would encourage you to also consider the Monaco Vesta. Similar size, front engine class A from Monaco. The main differences is it is diesel, has air brakes, an 8K cargo capacity and large towing capacity. As the only Class A ever designed with wind tunnel testing, it drives very well and gets good mileage. IMHO is kinda cool looking. Oh yeah, full disclosure, I own a Vesta.

Interesting Coach
This particular one was the prototype.
