We need to get trailer to move our children back and forth from college. We will be using trailer for many many years 15+. Looking at a 7x14 or a 6x12. Should I go with a double axle or double axle. Trips will be long but not alot of weight and I don't antisipate there being heavy loads very often. Will pull with our suburban and 3/4 ton pickup, but suburban on most trips. Any help with brands and size will be great. Thanks and HAPPY HUNTING
