We're seasonal. Because of my work situation, I (we) live in our TT almost full time from April through Oct (when the seasonal season ends).
First off a big big help no matter what type of site you're on (paved, gravel, etc) is to get some treated 2x10's to park your unit on. Some extra stability jacks under the frame will make a big difference as over time the unit will settle and wobbles and shakes will occur. Give it a month before you start jacking the heck out of it. I had 2 old railroad car jacks I got at a farm auction about 15 years ago and put one under each side, right in front of the tires and it made a world of diference in the stability.
A lot of seasonals will opt to put hard pipes in place of the plastic sewer snakes. We haven't done this yet, but it does give the advantage of not having to make sure the catepillers, hoses, connectors, etc are all in tact.
If you plan on putting on a deck, stairs, or anything else, make sure as much as possible you're unit is where you want it and don't build too close to the sides.
We try to keep our site tidy and neat, running the water, electric, sewer hoses under the trailer behind the wheels so our neighbors don' thave to look at all the pipes and such.
We try to be as courteous as possible, not leaving our outside lights on all night, keeping Scout from barking as much as possible, picking up after him.
Generally it's just like moving into a new neighborhood. Our CG has separate areas for seasonals, year rounders, and transients. This helps by keeping traffic down in the areas where the seasonals are.
Good luck with your adventure!
