Most common mistake people make is buying a tow vehicle based on fitting in the garage or how good the ride/gas mileage is when not towing. You should buy it based on how much it can tow. It only costs a few hundred more to upgrade to a 3/4 ton HD truck instead of the 1/2 ton and it will tow much easier. Especially the size trailer you are looking at. In fact I might be inclined to go with a 1 ton single rear wheel diesel. Better fuel economy all the way around and better resale value as well as being able to haul most any trailer you want when the kids start wanting quads or dirt bikes and you need a 15,000 pound toy hauler. Saves you from buying another truck.
In any case, the trailers you are looking at are borderline for 1/2 ton trucks and may be over loaded when you put your family and gear in. For a few hundred bucks it is not worth the gamble and towing at the limit of the truck is not easy or relaxing. If you don't think it is true, just look at the threads about how to add suspension enhancements to 1500 series trucks. There is always at least one here.
The lighter the large trailers are the flimsier the construction. Better built trailers will weigh 9000 pounds at 26' vs 31' for others. The weight savings comes from somewhere. For a well built trailer check out outdoorsrv.com Their standard features are things many people add and they are true 4 season trailers. There are other well built ones out there as well and since they hold up better the resale value is better.
Good luck with the search.
