I would suggest you get the Blue Ox Sway Pro, I just changed over from the Husky Center Line (same as Reese) and it is a bear to setup and may be a little uncomfortable on your tundra. It was for me on my Durango r/t.
The sway pro made it feel like I was literally driving a different truck. My only negative is that my sway pro does not eliminate sway as well as the husky Centerline. To be fair my test drive was in 30 mph winds that gusted to 40 when I crossed a bridge.
I will be posting a detailed review when I get back from my next trip.
I would highly recommend a Tekonsha P2, they are pretty much the standard. The P3 is about $20 more but I can't for the life of me figure out what more it gives me.
The Sway Pro was $560 on Amazon and I believe the P2 is about $120. My dealer also offered me the same $1000 deal but it was all bottom of the line stuff. The controller was a $40 item, the Weight distribution hitch did not have sway control built in like the Reese or sway pro, and the anti sway device was a simple piston that needed to be removed to back up.
I am assuming you have a crew cab to haul your family so your weight capacity might be very limited, you will want to check that carefully. If your trailer is 5,800 dry, assume it will be about 6,700 LBS loaded with gear. That translates into about 850 to 900 pounds of tongue weight on your truck.
Add the the hitch weight of about 80 lbs and you will be adding close to 1000 lbs to your truck before you even get in to the truck.
I don't want to sound like the weight police but cargo capacity is WAY more important than tow rating. I had to sell my a relatively new truck right after I bought my trailer because I didn't listen to the good people here.
Might I recommend you look at the Funfinder 242BDS? You lose the couch and one of the kids will need to sleep on the dinette but it weighs about 900 lbs less and I think you might find the top of the line appliances and outdoor kitchen very compelling for the price.
Good luck!
