Hello Tanya, welcome to the forum! I'm new here myself, so not an expert by any means. I can identify with your enthusiasm. I imagine you may have to learn to pack a little lighter than you're used to. Remember the people you'll meet at campgrounds will also be doing the same thing. Learn to layer your clothes for changing weather and plan to use the laundromats more frequently. You'll be surprised how little you really need, as opposed to want when packing. Look at the space you have available and make it work.
In basic training (Army) they told us we could get a whole month out of a single pair of underwear when in the field. I took it as a joke, but it did demonstrate packing light
. It went something like this...
Week 1, wear underwear normally
Week 2, turn inside out and wear again
Week 3, trade underwear with your battle buddy and repeat as in Week 1
Week 4, turn inside out and wear again
Disclaimer- I never did this!!
Have a blast with your camper. Ask specific questions and the generous folks on this forum will be happy to share. I hope my wife and I run into to you camping some day.
