Congratulations on your new to you trailer. Being bitten by the camping bug is a good thing. My best memories in life often revolve around camping.
My suggestion is to go to a large show where you can compare brands head to head. Keep in mind your towing capacity, payload capacity and invest in good quality towing equipment. Your safety is priceless, so don't skimp on a good hitch.
We had a Keystone Bullet for three years, and loved every minute in it. This year we went to a MH, and we're loving that too.
I hope your family has many fun camping adventures.
