How much does 30+ feet actually effect ability to find space

Well, if you are trying to fit into 'tent' sites, then yes, even my little 22' TT won't fit in most of those spaces...

But, if you are talking an RV park, or even state park "RV" sites, then you should not find any problems. If they do ask what size rig you have, then there could be issue with fitment but that's the reason they ask first.

The old national parks were not made for modern day RV's, so they may have more restrictive sites depending..

So, in the end.. There is no real answer to your question other than getting the RV you want and then deal with where you want to go.. Or if where you want to go is more important.. Find that out and adjust your RV to those specs.

Good luck!

I'm 40' and never been turned away. With my truck hooked up I'm more like 58' and still never been turned away from a campsite.

I think 34' would be okay most of the time. Several years ago we had a 33' motorhome. We preferred state parks and were able to fit in most of their sites. Part of the reason was because with the 4' overhang in the rear, we could back in and fit in a 29' site if need be. We also didn't have any issue navigating the roads in the parks at 33'.
With the current 40 footer, we have to pick and choose which parks we can navigate and less sites available at this length, but we like the extra roominess in the 40', so we deal with less availability.

We do have a 24 footer that we use in older forest service campgrounds when the 40' just wouldn't cut it. I think you will be fine with a 34 footer at most campgrounds though.

It really depends where you are and what sites are available. In many cases, it is not a significant detriment. In some others, it may very well be a significant constraint.

That being said, if you are looking for sites with hookups, you will generally have no trouble at all finding large enough ones; it mainly is a problem in older, often public, campgrounds which were laid out before large RVs were common. Many of the Vermont state parks are examples; in quite a few only a fairly small percentage of the sites will accommodate a 35' RV, and if those few sites happen to all be reserved or taken, you're out of luck.

My motorhome is 32' bumper to bumper and, while it has been a limitation a few times, I have never been unable to find a suitable site when I wanted one, though I have had to be a little bit flexible a few times about where I wpuld go. On the whole I wouldn't worry overly much.

It's also true that, no matter how big or small your RV, there will be some sites you just cannot use; and naturally the larger the RV, the more sites you won't fit in. There isn't really one length where it suddenly stops fitting, but a gradual progression. (Probably the biggest single step down in availability occurs when you go from a tent, and hence can use any walk-in site, to using an RV of any sort that must have drive-in access.)

Depends on where you want to camp. Where do you want to camp? Many California state parks...you’re too long. Many USFS campgrounds on the Eastern Sierra...you’re too long.
