Escapees out of Texas handled our mail (full-timers) for about three years. Early on there were problems getting things in a timely manner due to an overloaded North Houston mail hub, but that seemed to smooth out a couple years ago. I liked their scanning service, but they thought it more of a temporary thing and kept turning it off and making me turn it back on. That may have since changed, not sure.
We bought an RV lot in Florida and decided to use it as our address. When we are out for less than a month, I'll let the USPS hold our mail. This summer we used their premium forwarding service ($18 a week even if you have no mail) and were not fully pleased. When we got home, we had a nearly full mailbox (with random older mail in it) and had some older mail that had been held at the post office. That means the carrier didn't always put our mail in the stack to forward each week.
This is somewhat speculation on my part, but I believe for domicile purposes and insurance ratings that the Escapees mailbox option looks like a business address. When we "moved" to Florida and used a pure residential address our truck and trailer insurance policies dropped 40% each and our car's policy dropped 30%. Our health insurance (ACA-compliant PPO insurance plan) dropped 50% (you read that right - Texas has onerous health insurance requirements over and above ACA requirements).
