As a member here for more than 7 months, the one thing I've noticed are a lot of questions to compare renting an RV to traveling in a rental car and using hotels/restaurants.
In the many resources here at RTA, there is a WONDERFUL article that may be easily lost. This article compares the two ways of road travel. As one who is "between RV's" at the moment, and have done both RV and car/motel road trips, I can say that this article is RIGHT on. Go to the second page and there is a Pro and con for each mode of travel. Here is the article.
When we travel in the car and stop at a motel every night, we have the following issues: First, we get very tired of restaurants. We did better this past trip, trying to stay away from the chains, but restaurants still get tiring. If you're trying to watch your calorie or fat intake, it's even more difficult at a restaurant. Keeping snacks and drinks in a cooler in the car is nice, but sandwiches will get old after awhile, and salad makings die in a cooler after the first day or two. Trying to cook in the hotel microwave is difficult unless you eat frozen meals every night (which also gets about as old as restaurants). On top of these considerations, restaurants are just plain more expensive.
The motels have their headaches too. In an RV, you know who slept in the bed last night (unless it's the first night in a rental), when the sheets were changed last, when the bedding was laundered last, and you don't have to unload the car every night. (However, you MAY need to hook up to the hookups, or back into a site.) As the article points out, some campgrounds can be just as expensive as cheaper hotels, but they are friendlier. Rarely have we ever stayed in a campground or RV park that made us nervous, but that's happened several times with motels.
Anyway, if you're debating which method to use for travel, take a good look at that linked article.
