I would be wary of carrying a knife with you while out of your van. It might make you feel safer but carrying a weapon in public can land you in a lot of trouble. Maybe swap the knife for an alarm, a loud noise is usually enough to scare off anyone.
For added security in your van, .Ii have read posts on other websites of people tying a cord between the 2 front doors. This stops the doors from opening while your inside and might be a cheap option to try. On the rear doors then a simple door bolt, see how vandog did this on his van, will stop the rear doors from being opened from the outside.
