The 6x10 trailer with the FEL up on the rear gate will get you a ticket in most states for an unsecured load.
I can about guarantee that you will eventually get a rear blade and probably an FEL for your tractor (more useful than you can ever imagine!!!) and your short trailer won't cut the mustard. If you go with a 12 or 14 foot trailer now, you will be happier. It will also give you many, many more uses. It is well worth the extra money.
