Just bought our first RV and planning on a seasonal site from April-October. Except for a couple week long stays we will only be staying in it on weekends or perhaps every other weekend. I was wondering if you pull your slides in when you're not staying in it or if you leave them out. It almost seems to me like leaving them out would create less opportunity for leaks to develop in the seals but our salesman told us we should bring them in every time we leave. Any advice? Thank you.
