Yep, you should be fine with the width. When you make your reservation, make sure you tell them you have slides and awning - usually they ask anyway. I can't think of any site in the 1600-1900 loops that wouldn't accomodate your rig. You might have to make sure your slide will open with the utilities post, if not you might have to move up or back alittle bit. We sold our 5'er w/3 slides last year and we never had a problem with getting into any one of those sites. We love the full hookup sites - lots of room and all 4 loops are pet friendly.
