One of the reasons I upgraded from tent camping to a camper trailer was the kitchen.
Started off with everything in a few plastic tubs. Would have to rat around just to find a spoon, hated it. Then I bought a collapsible cupboard so that I could unpack the main cooking equipment and food into it, that worked much better during camping and it meant that everything was closer to hand that even the kids could find it!
But
It also took alot longer at setup and packup, building that cupboard wasnt always easy - though they do have instant cupboards now. Also I would have to unpack the stuff out of the tubs into the cupboard which meant double handling and extra time. Packup was the worst part, I would have to empty both the cupboard and the tubs and then jigsaw the gear back into the tubs, this part was time consuming and I hated doing it.
On its own it probably wouldnt be to bad but then our family took a fair amount of stuff, bedding, kitchen, tent, sometimes toilet and shower tents (you know the instant ones that are easier to abandon at camp than to try and wrangle, fold, spin and twirl back into the circle shape!) esky, chairs, tables ect that all had to be packed down and carefully arranged into the garden trailer. It could take hours
When we bought a camper, I wanted all the kitchen gear to be close at hand so I didnt have to worry about it, just pull it out at the start and close it up at the end. Most of the campers we looked at (budget end) didnt have a kitchen that would allow that to happen, so I ended up adding a Drifta DPOR and I love it. I open it and I close it! Still have to spend time packing all the kids bedding, but some things I will never get away from I think
Alot of swaggers have made their own kitchens that include plenty of storage, have a look in the build up thread there is plenty to learn.
