Being in a riverside community we have a community boat launch, fishing dock and pick-nick tables available on the water in common areas. We are a few blocks from the water on very high ground. Our location is heavily forested but our property is mostly cleared. We have a 20x20 pallet deck with lawn furniture and gas grill available for guests. There is an area that is fenced that a pet could be put in as long as they are chicken friendly.
I'd guess any rules we might have will develop as we experience guests. We would request that any smoking be done in your rig or in the ample public area that will be available including the pallet deck. Just don't leave butts around and stay away from our house and deck while smoking. Loud generators could be a problem so use should be no later than 8pm I'd guess. That is probably a case by case basis. Right now I don't see the need for any hard and fast rules about departure. If everyone (host and guest) is happy I'd expect some might like to stay a day or two and fish or just be off the road and relax for awhile in a safe place.
The subdivision has fairly narrow blacktop streets. We have never had a problem getting our Class A to our property. I don't anticipate any problems.
Parking should not be a problem for most rigs and tow vehicles. We have a long wide drive for larger rigs and two extra driveways for vans or tow vehicles if we need them.
Within 3 miles we have a few great eating places and a small grocery and the all important Dollar General where you can buy pretty much anything. Within 15 miles is Huntsville, TX which offers most of the big Restaurants including some great Mexican places (my favorite). There you can also find most of the big box shopping places as well as an RV repair shop. There are also museums, Sam Houston State University and beautiful parks. Sam Houston State Park is very close as is Lake Livingston. There is also an Indian Casino about an hour from us which is a beautiful drive and they have an RV camp ground in the woods on a small lake which is beautiful. The Escapees Club is in that general direction as well.
