Just practice "good sense" driving.
Each time you stop, do a walk around and make sure all the tires and lights are fine. Check the hitch on the trailer and see if it is still tightened up.
Do not go thru drive thru's as some vans will be too tall and cause damage.
Only park where you can pull out instead of backing out. Use your turn lights every time and put them on well in advance.
If you have a gps I would suggest using it as it will notify you well in advance as to which lane to get in.
Stay out of the far left passing lane unless it is really needed.
Try to look at traffic far ahead and give plenty of space between vehicles.
Good luck and have a safe journey.
