good place?

Planning again for next year. Looking for reasonable rates in good Portland/Vancouver area for month of July. Last year stayed at 99RV. Not bad good monthly rate but felt cramped. Would like something in $400 $500 including full hook ups. I have a German Shepherd who is my service dog, 99 RV gave me a hard time when we first got there but they said we could stay. We have a 38" Winnebago with 3 slides.
Thanks
