Getting 5th wheeler next week

I switched from a 35' TT to a 42' FW last year. Best advice I got was to go to an empty parking lot and set up some red cones. Make some turns without hitting the cones so you can get use to how FW tracks the TV. Then set up 2 cones to represent the opening of a campsite and practice backing in from both directions (driver side and passenger side). Practice, practice, practice. The FW will overall tow better than the TT.
