Welcome to the forum
In my opinion FWIW you cant go wrong with a crew cab. The extra cab room is great.(We moved up from a extended cab to a crew cab this spring and do not regret it.)
We looked at Fords,Dodges,and Chevys and they are all capable trucks.
If you have a vehicle preferance then go with that,or take your time and shop around to find what you really like. Just make sure that you get a big enough motor and the towing package.
Also if you are looking for a half ton PU check the payload sticker on the door of each pick up to make sure it is capable of hauling you and your family and the tt and gear.
Happy Camping
