Welcome to United! Denver actually wouldn't be too long to hold as a base. It's come down quite a bit in the last couple years. If you could hold out and bid it on the 737 at your first shot, it shouldn't take too long. Also the guppy flies a lot of Hawaii out of LAx and SFO. As your seniority allows it, you could bid Hawaii overnights.
That being said, I made the move to my domicile and haven't looked back. Living in base is a dream, especially above the g line. West coast is going pretty junior, but I get the tax issue. How much is your time at home worth to you?
