Packing for 3+ months on the road

Packing our 35 foot travel trailer will be a challenge as storage space is of course limited.  We have our normal kitchen stuff and linens always packed, it's just the food and clothes that are left.  I started a list 2 months ago as I thought of things I wanted to take along.  The hardest part of deciding what to take is remembering the everyday things you don't even think about until you need them. That is the challenge! We have extra bedding in case we get any visitors- they can use our pull out coach/bed.  We have already purchased an extra tower electric heater for those cold Arizona nights to save on our LP gas.
