Thanks everyone
Yes, I did wonder how they would fare during actual travel. They are a fairly tight fit so I'll see how they do, but my backup plan is to secure them in place with a strip of fabric across the top of the bottles, secured with some velcro on the side of the spice trays.
Although I'm thinking it will definitely take awhile to go through that amount of spices, we do love to cook when we go camping.
Next I'm on the lookout for a good used dutch oven to add to our camping gear. There are tons of dutch oven/camping recipes online and I'm excited to try some! (over the fire)
