I've stayed at Winngray several times and didn't have any issues with them. Also an excellent restaurant in Waynesville is Maggie's Galley,, and if you're looking for higher-end dining, try the Old Stone Inn.
X2 for Bayou Signette State Park. It's been a while but, we enjoyed our stay there. We did not like the campgrounds on Chef Monteur Highway, if they are still even there. In fact my wife refused to stay there, which is how we got to Bayou Signette. :-D
Not wanting to sound like a hollow drum, but check on Mr. Bruni's GEO Method. If you need to use our gauges, it will help more than anything I've tried. Barring that, I agree with Skip, after a while you'll develope a feel for when you need to dump, and probably never look at the gauges. The toilet "burp" is a sure sign.
My driveway/trailer parking area has a slight side to side slope. So, I use boards under the low side and nothing under the other. I have noticed no difference in the servicability of the tires. But, that's just my experience, your results may vary.
If you get a short-bed, you may need to get a trailer with an extended hitch box, or get a slider hitch for the truck. The width of the trailer, from center is wider than the distance from the hitch pin to the back of the cab, so if you turn too sharply you can damage your truck and/or trailer. In my opinion, it's not a lot more of an issue than jack-knifing a tow-behind trailer. Lot's of people do it, and with a little care, don't seem to have too mauch of a problem. On the other hand, I do have a long-bed, and have gotten into situations that would have been an issue for a short-bed truck.
Do check, because some manufacturers will void your warrantee for a double tow. Like others have mentioned, some 5'ers come with an optional rear hitch. My dealer recommended I stay below 150 lbs tongue weight on my double towed trailers.
From my experience no matter what you plan, 16 and 18 year old teens will think it is lame. We've enjoyed staying at the Playful Goose in Horicon. Horicon is where they make John Deere lawn tractors, and is home to the Horicon Marsh, the world's largest reed marsh (so they say). My grandchildren enjoyed the pontoon boat trip out onto the marsh. And we did enjoy touring some of the cheese shops and cheese factories in the area. Oh, and there is a meat market in Horicon, that I don't remember the name of, that makes some great bratwurst.
The smoke can get quite bad at times. You have to be especially careful when travelling during foggy times. The combination of fog and wildfire smoke can be deadly, much more thick and intense than regular fog.
If you have an outside shower, or an inside shower with a shut-off at the shower head, make sure your valves are fully shut off. The showers can act as a mixer and blend hot and cold water, and usually cold is the shortest path for the water to take. This seems to be a commone problem.
411 is a nice drive, although a 2 lane highway, with several small towns. As for Atlanta, I would recommend going straight thru on I-75. The bypass, I-285, has way too many trucks. Stay in the dead center of the interstate when going through. The right lanes will exit on you. If you have more than one person in your vehicle, you may want to get into the left carpool lane. If Southbound, stay away from the morning rush, and mid to late aftrnoon, as it can get quite congested on the section called "The Connector", from where I-75 and I-85 merge until where they separate on the south-side of town. Unless there is an accident, you may find that the speeds can be quite high. Also be aware that the lanes are quite narrow for a wide vehicle such as a camper. They added lanes without expanding the overall width of the expressway, by narrowing the lanes. Since I live near there, I've done it a lot, and in my opinion, even at it's worst, it's still better than Chicago.
Disney fun fact, you don't have to get the buffet at Trails End. If you want somethng lighter, you can request to sit in the bar and order wings and/or nachos which were cheaper than the buffet. The wings were great, and the nachos were ok. Or you can get a pizza for take-out. The pizza was good.
If you're on a budget, and can be flexible on dates, you can get reasonable rates during a less busy time of the year. Stay away from spring break or peak holiday times. Eat a meal or two in the camper to save money, and drink water instead of soda or iced tea. Water is free in all the quick serves or sit-down restaurants. That alone saves a bunch.
Time saving tips:
-Never go to The Magic Kingdom on Monday - busiest day
-At Epcot, don't stand in line at Spaceship Earth, hit it in the afternoon when there are no lines.
-Hit the popular rides during the parades, or when the large shows are in progress. Never try them right after a show lets out or a parade ends.
-Use the extra magic hours, to hit as many rides as possible in as short a time as possible.
- Get a Fast Pass for the most popular rides
-Watch the crowds, and go the oposite way.
-If you go into a park and it is real crowded, go to a different one, it may not be.
These have worked for us.
