Howdy,
We pull a 6' X 10' Pace enclosed trailer with a Ford F-150 extended cab 4-wheel drive that has a truck cap. In the trailer we carry enough poles, stakes, ropes and and canvas to set up 2 wall tents and flys, a one-pole. and a 11' X 17' marquee at the same time. We do not do this of course, but depending on what size event and lengh of stay, we are pretty well ready. We also have bedding, tables, chairs, lanterns and their hangers, clothing and kitchen supplies. In the truck we carry firearms and their possibles, water, food, coolers and the last minute things.
We used to pack only the truck each time we went out and that gets a little old. We like our trailer very much. We sold our pop-up trailer and used the money on the Pace. One of my good friends is a blacksmith and we installed 3/4" plywood on both sides inside and he made a set of racks on one side for the poles. We put 3 shelves in the front for misc. items.
If I buy another trailer, it will have a side door as ours does not and it is kind of unhandy if you need something clear in the front.
