Along with your budget, some other things to consider:
What is the type of trails you run the most, i.e start at one end, camp along the way, and exit the other side, or start and leave from the same area.
Is there ample parking and place to turn the trailer around at the trail heads of the trails you run?
When you do hit the trails would you be leaving your rig unattended over night?
Do you do you have the storage space for a trailer queen and tow rig.
Will you tow enough other things to justify the added costs of a rig that wont hardly get used?
Just about all my buddies got bit by the trailer queen bug 5-6 years ago, most of them that have stayed w/the hobby have dumped them and gone back to street-to-trail rigs, and seem to prefer it over the towing a trailer.
