First I want to mention that this is speculation, given that we aren't actually living Vita In Via (life on the road) yet. Camping is easy, for a limited time we can manage just fine. Full-timing will be different, I'm sure, even though we haven't done it yet I can still somewhat imagine how different it will be. And I won't know for sure until we're actually doing it. All I can do it try to plan the best way I can, and then be flexible when the time comes.
Second, we have lived a low carb lifestyle for 8 years. Our pantry won't be full of pasta dinner kits, no pot pies in the freezer...we don't eat packaged food very much (exception being the occasional frozen pizza - a weakness of ours!), and I cook from scratch. However, this is also a good thing, not only for our health, but also because there are a whole lot of foods that we don't have to make space to carry: canned soups, breakfast cereals, frozen dinners, loaves of bread, crackers, cookies, cake mixes, etc. And because we eat mainly fresh, a lot of our food doesn't have to be stored at all! Farmer's markets, roadside stands, produce markets, butcher shops all carry the fresh meats and produce that we live on, and buying just a few days' worth at a time means no long-term storage space for the majority or our groceries! These will take up fridge space along with our eggs, butter, cream, and cheeses.
Baking supplies will be the main storage issue, I believe. And baking is a bit more interesting when it's low carb. I don't just have a bag of flour and a bag of sugar and a few spices in my cupboard. I need a combination of flours (almond, coconut, gluten, fibers, protein isolates, etc.) to achieve good results. I anticipate that these will take up a good portion of our cupboard space, along with other baking ingredients (baking powder/soda, sweeteners, extracts, etc.) and spices.
Counter space is at a premium in these travel trailers. I can certainly use the kitchen table as a workspace, which will help somewhat. And I will have to be training myself to clean up as I go, as well, since I won't have 5' of spare counter space and a huge kitchen sink to stow my dishes until I'm done. That is something I can start working on now, developing this habit.
Cupboard space is also limited, so I don't know that I'll have every different type and size of bowl or utensil or baking pan available to me; where would I keep them all? Now, I can use a dozen different items in just creating a single meal. In a TT I'm wondering how much space I'll have for these?
And this brings me to another feature that I see as almost a necessity: a pull-out pantry (or 2!). I can't imagine, when I'm in the midst of a project, having to drag out everything from a shelf and find a place to set it, so that I can get to something I need way in the back! Ugh!
One good thing: GRILLING! Grilled meats and vegetables, and even baked goods such as flat breads, will be done outside. My husband is an expert on the grill, and the ability to grill many of our meals will definitely be a godsend!
For budgeting purposes, I will have to shop differently as well. I stock up on meats and frozen vegetables now, filling my freezer so that I can "shop" daily from my stock for that day's meals. The more often I go shopping, the more I spend. Typically if I go to the store just for 3 items that I need, I come out with about 20 items. And my grocery budget goes to the dogs. Since I won't be shopping the same way, this is a problem I will have to work on!
If you are interested, I have found a couple of video resources for cooking in an RV:
The RV Cooking Show is put out by Evanne; she and her hubby also blog about full-timing for younger RVers.
George Murphy is the RV Chef. I haven't watched many of his videos yet but like what I've seen!
There are also numerous single videos that some RVers post, as well as numerous blog posts. I'm making my way through them as I have the time, trying to learn all I can from those who already have the experience I lack.
Food is my passion. Shopping, creating, cooking, feeding people - I love it all! And definitely this is something that I will need to accommodate when we purchase our RV home when the time comes. So it's something that I'm already thinking about (one of the many things!) and planning for.
