Thanks for all the replies folks. I'm a school teacher that has a side business doing mobile laser tag in the summer/weekends when the weather cooperates. As of now, when I have all the stuff (I have a business partner who has a minivan and all the stuff fits in there) I take the trailer because it's just easier to load the stuff in there and get out quickly after a party. Plus if it rains the stuff is dry anyway inside the trailer. Even with an XL I'd still take the trailer. We've done many events/parties with our electronics inside the trailer which has saved our butts and allowed us to keep the party/event going despite weather.
It would be great to keep both but my truck just sits anyway now because I bought a gas saver. I don't really have room for another trailer but have a buddy right by me who has a small 5x10 or something like that which I could access whenever.
Keep the replies coming!
