Welcome to the forum, this is a great place to come learn what you need to know about this way of life.
What kind of rig are you getting or already have. We can often give you more specific help if we have that info. One thing you will need whether you have a TT, MH, or 5th Wheel is a water pressure gauge and in line filter. These can be put in your utilities bay and are not that expensive. You can get both at Walmart for under $25.
CG's (camp grounds) are notorious for having higher water pressure than your plumbing in your rig can stand, don't want to blow your plumbing. The water varies too so the filter will help keep your plumbing and holding tanks cleaner.
You are going to have a great time. Like was said, check out the Fulltimer's thread and read as many old threads as you can. All are loaded with information that will help.
Love the sunshine and warmer weather!
