Guess I have to weigh in...
I would never EVER under ANY circumstances buy another RV without an outdoor kitchen. It is worth it's weight in gold 10 times over. It's the single greatest thing that has happened to RV's since slide outs. It's absolutely without question a MUST HAVE for me.
Then again, I tent camped my whole life, we always set up our own outdoor kitchen. We cooked everything outside, 2e had no other choice. Now that I have a TT, I also cook outside. I prefer it. If it's raining and cold, I'll still cook outside, that's half the fun for me. I've never used my inside kitchen, other than the fridge.
Havi ng a sink outside, AMAZING. Having a fridge for drinks outside, AMAZING. Having cabinets outside for random items, AMAZING.
Not sure if I made myself clear... I love my outdoor kitchen.
