For me, if you have the option to store inside I too would go with it! Mine is in our barn and the spring get ready for camping season is minimal. Same as for winter storage. I dread the day I have to store mine outside.
Things such as
tires, gel coat, interior fabrics, etc have less wear and tear from the elements...
Proof, went to have the
tires checked, the tire guy told me I didn't need new
tires.....
My truck, well that's a whole other story
and a thousand dollars later I got great tires......
