Cathy and I vacation in our 28' travel trailer with the trike or a bike in the back of the pickup truck. We generally stay at a KOA with a full hookup. The cost runs anywhere from $30-$50 per night. KOA also offers rough camping (elec only), generally around $20 per night.We like KOA because the quality of the campground is less haphazard than other options, but it generally costs a bit more than the state park or other private campgrounds.I hope this helps!athy and I vacation in our 28' travel trailer with the trike or a bike in the back of the pickup truck.
