While I don't share your enthusiasm for the draws, I agree on their convenience if it suits the person. Especially for longer travel / trips. I loved my draws at the start, neat and tidy setup. Especially cause I got them basically for nothing. But as time went on they began annoying the s**** out of me. lol
Rossco nailed it, what works for others is a nuisance for the rest.
I've always used tubs, usually el cheapo bunnings junk, then later on upgraded to dearer longer lasting units. Call me a tubber if you will. lol Even after I got draws, I found my self packing food in a tub like I've always done. And at camp that food tub comes out and sits next to my table / cooking setup. This eliminates constantly going into the rear of the car, opening doors, draws, and rear bar swing away units ( another nuisance separate subject). If I'm staying for longer than a day / night I usually take the fridge out as well, especially in summer, so then none of it sits in a hot car. Easier access.
And being a daily driver, when I come home those tubs come out in minutes and sit in the garage ready for next time.
