Heading west?

How long it takes really depends on what you intend to do and how long you take to do that. I guess there are some practical hard minimums based on driving speeds and times, but even so what's a reasonable minimum length for such a trip varies a lot based on who's driving (and if you have more than one driver to share the duties).

Personally, I'd likely plan a minimum of five days each way between CT and one of those states, which leaves basically no time for doing anything along the way besides eating and sleeping. (Four days might barely be possible for me, depending on the final destination.) Anything much less than about three weeks would seem to me to not be worthwhile for the trip, assuming the goal is tourism/vacation; with less time, I'd opt to fly or take Amtrak out or something, or choose a destination closer to home.

You, of course, may cover more or less distance in a day comfortably than I do.

We went on a western jaunt from SC a few years ago. Spent a month. Not nearly enough time to have a relaxing trip. If you like driving 6-8 hours a day then perhaps you can do all you want in that timeframe.

When you look at distances, a good rule of thumb (and also easy math to do in your head) is an average of 50 mph. Not that you'll be driving that slowly, but once you figure in stops for fuel, food, bio, etc, it comes out to about 50 mph.

Next, figure out your personal preference for driving. How far do you like to drive in a day and how many days in a row do you feel like driving? This will determine how far you can get with your available time.

Another variable is what kind of camper are you? Do you like to stay in RV parks, state parks, COE, boondocking, etc.? Do you make reservations and stick to a schedule, or do you like to wing it?

My wife and I took an 11,000 mile trip year before last without any solid destinations or reservations. We never backtracked, which gave us three general compass points to choose from on any travel day (ruling out the direction we just came from). The night before a travel day, I would pin my wife down to a general direction and then I'd glance at the available places to stay in that area. Then the next day on the road around one or two in the afternoon I'd start to bug her to pick us a spot and call ahead to book it. I don't think we could get away with that during the current RV boom though.

And yes, this probably isn't the right place for this question. The Roads and Routes forum is really for directions and suggestions for getting to Point B from Point A. I'll move this to General RVing for you.

Look up average temperatures in the areas where you plan to stay. You may wish to "go higher" which is usually cooler.
