Welcome to The Forum! What model(s) are you considering?
Take your time with your search to make sure you select the unit that best suits your needs. After all, the search is part of the fun! Don't "assume" some doohickey in the Jayco works just like the similar doohickey in your old trailer. These things and their systems are constantly being improved upon. If you have any questions, feel free to ask. You'll find the members here are super willing to help out a fellow RV'er whenever we can.
Enjoy your search and post pics of your new rig . . . even if it's not a Jayco!
