I have a co-worker who purchased a 40 foot 5th wheel to live out of. We are on projects that last 5-8 weeks at a time. Depending on the location and time of the year, sometimes it can be a real PITA for him to locate long term parks to setup in. You would be surprised at how many times the campgrounds are booked up for various reasons such as state fairs, all sorts of regional festivals, sports events/tourniments and so forth.At times he has to setup 40-50 miles from the project site. Sometimes I even acquire monthly hotel lodging cheaper than he can rent a concrete pad w/electric due.
I know he now regrets the purchase of said lodging due to the amount of maintenance/upgrades to the tow vehical and all associated aspects of "camping" that comes with it. Even the most "winterized" packages will run you in the ground keeping them warm during a Dakota winter.
One of his 1st lessons was just because your hooked up to a full service site, you still need to keep the holding tank valve closed, if not all the fluids will drain and leave the solids sitting in a pile. Right before you travel drain the tank and drop in a 20# bag of ice, as you travel the ice will scrub the holding tank and loosen up the "stuck solids" before melting.
Congrats on your new home, hope you enjoy.
