We have a 2007 3326 king and bought it 3rd hand in 2011. We waited for a year till one came up on the for sale lists on this site.

We have a Toyota 4 Runner V8 that delivers between 12 and 14 mpg depending on the winds.

Regarding your kayaks, we found that Thule makes a "Haul-a-vator" system that allows you to load your boats at waist height and then with gas assist raises it to the top of your vehicle.
It works great on the roof of our 4 Runner and I would recommend that you mount yours on your truck as well and not the roof of the Trailmanor.

"Happy Camper" is a really well liked and recommended additive and comes in powder form and very economical. We bought our first supply from Amazon.com.

The 3326 King is not in the catalog but can be special ordered and this comes from the factory when we had ours in for a tune up.

Good luck. N.
