I'm looking for some TT advice from experienced RVers

Thanks for all the replies. We just pulled the trigger and bought a new 2019 FR Flagstaff micro lite w/ Murphy bed. I will pick it up in several days and be traveling home to Sedona. The grades on I-17 from Phoenix will give me a test of my F 150 5.0 L RWD truck. I will be using the Anderson WDH and hope it performs like the reviews I have read.
What was interesting, the AZ dealers wanted about $3000 more OTD than other states and we got one in So Cal believe it or not for our asking price!
