Ron, every time I've seen photos of your storage compartment I'm envious, and not just because it's immaculately clean! I think the slide-out drawer assembly is a bad design as the weight carrying capacity is far less than what can be stored in yours. Mine is already "cocked" with one side never wanting to go in as far as the other - it needs to be pushed in, then secured with the latch to stay in place. I haven't been able to adjust the glide rail so I just limit the BIG spacious drawer to carrying lightweight supplies and accessories with heavier items like my Blackstone griddle on the shelf above.
I only seen the drawer systems on-line, never in-person. But I always thought they were a marketing ploy. They sure look nice and organize your stuff better. But for our needs, a bigger compartment is better utilized and also better sealed. I honestly think Irene and I could both get inside our exterior storage compartment and close the door. It is that big.
In an odd way, I place exterior drawers in the category along with slide outs. They are not attractive to me given our plan to keep our PC until we are no longer safe drivers. That is hoped to be at least a 35 year ownership. I don't think I could get 35+ trouble-free years with slide-outs and exterior drawers. But at the same time, slide-outs and drawers can keep working with enough owner-determination. I am simply attracted to simplicity.
The 2350 exterior storage compartment got smaller with the drawer, but got smaller yet when Phoenix relocated the fresh water tank forward and centered for improved weight distribution and for improved vehicle handling. So there were sacrifices made in storage for gains in other areas. That is why it was even more important for our 2007 E350 chassis to have the aftermarket heavy duty suspension upgrades to counter-act the 300 pounds of fresh water sitting in the right rear corner of the motor home, along with the extra weight placed in that storage compartment. Every benefit has it's gains and losses. I am fortunate to have a solution to address my losses via suspension upgrades.
