Do you include O2/moisture absorber desiccant packets in your homemade meals?

I'm a trail meals newbie prepping a bunch of large dehydrated meals for a 4 person canoe camping trip in a month. I'm dehydrating my own veggies and chicken to make these meals using an ancient one setting food dehydrator, so I'm trying to be really careful and keep everything in the freezer until we're ready to go. I'm using gallon ziploc freezer bags for storage. Do you all recommend adding desiccant packets for extra assurance? If so, do you have any links/brand recommendations?

Also, I've read that O2 packets and moisture packets have different uses (grains vs fruits/vegetables), but my meals will be a mix of both. Any help is appreciated. Thanks!
