More insulation everywhere! Cab in particular, floor, doors, front cap. Go with the double pain windows, e-450 chassis, forget the in dash navigation. I would go with the light hickory wood, I am getting sick of the dark cherry, see if they offer a theater set up for the sofa seating, slide is a must. I do like the ladder but no roof rack approach. Full body paint looks super but it sure is a lot of money just for looks. I would have PC install any and all suspension upgrades you can afford, new shocks, front and rear stabilizers, trac bar. Guess that is it from my perspective. Ron G.
