As of right now, there are well over 10 million RVs out on the road today, with RV ownership on the rise in nearly every state. It stands to reason that RV lots are going to become more desirable as time goes on, whether for ownership or just a summer rental. But how big is an average RV parking lot?

In an RV park, the size of an RV parking area is around 20’ wide by 40’ long. It should be more than enough to accommodate even large RVs for short and long periods. While you may find that some are bigger and some are smaller, it’s a safe bet that 20’ x 40’ is what you will get most of the time.

The average width of an RV is 8’6”, leaving you a good 11’6” of side space assuming that you park your RV right on the edge. Even the largest RVs (Class A) are 33’ long, but since the width is more of what you’re concerned about in an RV lot, length isn’t normally a problem.

What are the RV sizes and limitations?

If you’re considering an RV lot or even getting an RV, knowing the various sizes that RVs come in will serve you well when it comes time to pick out a lot. There are several classes of RV, and there are also width limits in certain states.

Only Hawaii allows RVs to be as wide as 9’. If you’re in any of the other states, you will have to obtain special permissions or face fines if anyone of authority ever cared enough to come out and measure your RV.

Length doesn’t seem to be as much of a concern with individual states. This is especially true since Class A RVs pretty much top out at 33’ long.

Class A RVs

These are the “king” class of RVs, in much the same way that a King or a California King is the biggest mattresses that you can buy on the market today. Class As are extremely long, bulky, heavy RVs that are usually the most luxurious RVs of them all.

Fortunately, since most of your RV lots are 40’ x 20’, there is more than enough room to accommodate an RV of this size. Class A RVs are usually 12’ to 13’ in height and are the maximum allowable width according to the state laws in which they are manufactured or shipped to.

There’s no doubt that this juggernaut is a luxury in the spacious interior, and of all of the Classes of RVs, this one will eat up the most space on an RV lot. In fact, if you are thinking about purchasing an RV lot, you may as well build a deck in the remaining space.

Class B RVs

Believe it or not, for some bizarre reason or another, Class B RVs are the smallest of the bunch. Whoever decides these things must have fallen asleep during the “logical descending order” class or “ABCs” class.

Class B’s are roughly 20’ long and between 7’ and 9’ in height. However, a Class B can match either an A or a C in terms of width, and they are usually 8’ wide. In a 20’ wide lot, you’ll have around 12’ of side space, assuming you don’t have any slide-outs to complicate things.

The best part about parking a class B in the average RV lot is that if you squeeze it into the corner, you will have the side lot area and a pretty sizeable front or rear section, depending on how deep or shallow you park the RV.

Class C RVs

These RVs fall squarely in the middle, tucked in between Class A and Class B because nobody knows why. Class C RVs are usually 28” long and, like A and C, are generally 8’ wide but are known to be as wide as 8’6” in states that allow it.

With the maximum width, you will have a little less space in an RV lot, but it’s doubtful that you would notice the difference. With a maximum length of 28’, it’s possible that you could have close to the same amount of front and side real estate on an RV lot if you parked the RV perfectly.

Is RV lot ownership worth it?

If you own one of the massive, Class A RVs, it may not be worth it outside of having a relatively large parking spot and little else. Outside of that, there are some compelling reasons to go all-in on an RV lot.

  • Seasonal home
  • Makes financial sense if you camp there often
  • RV lots appreciate in value
  • Community
  • Amenities are usually pretty nice in a campground

There are some other good reasons to consider it as well, but only if they make sense. For instance, if you purchase a lot in a campground, do you have to pay extra for the amenities there? Sewer, water, maintenance, cable, internet, and POA dues (Property Owner Association) may fall into different categories.

You may have to pay monthly costs on some of those, even if you spend a good part of the year living somewhere else. It’s worth the time and effort to hunt down RV lots for purchase, where many of those amenities are simply there for the taking, rather than an added, monthly expense.

One of the biggest reasons that people purchase RV lots is that it provides them with a seasonal home. Let’s say they’re from Florida and retired. Wouldn’t it make sense to purchase an RV lot in a northern state with a milder climate and live there during the sweltering summer months?

There’s also the point that some RVers love to park their RV in the same campground, racking up substantial rental fees over time. If enough time goes by, it may be that the rental fees surpass the actual cost of the lot.

Community is another good reason to consider an RV lot. If you live there off and on throughout the year, you will doubtless make friends and meet new people. RVers are nothing if not hospitable and highly social folks. It’s just a matter of time before you feel a sense of belonging in that community.

What’s the difference between an RV lot and a campground?

While both an RV lot and a campground are the same, an RV lot typically comes with amenities that other camping lots lack. For instance, if you are out there pitching a tent, it’s hard to imagine a reason why you would need a sewer hookup.

If you’re in a tent, you’re also not going to get an electrical or water hook up, outside of the possibility that there might be a water faucet nearby. RV lots get all of these things and more. Tent lots are typically a little more primitive in location as well.

You will most often find that tent lots are farther in the woods, laid up on the side of steep inclines, lack any kind of paving, have large fire pits, or have small, rectangular parking spots made out of the gravel.

If you’ve been to plenty of campgrounds, you’ve probably run into a tent lot next to an RV lot. The difference between the two is pretty striking, as the RV lot and the tent lot are simply designed to cater to vastly different camping styles.

Are there larger RV lots to choose from?

In most campgrounds, you can fit about 15 RV lots into a single acre so that’s pretty packed in there. It’s about what you see in those new neighborhoods where you can practically slide your window up and breathe into your neighbor’s window.

RV lots can be as small as 18’ by 9’ and as large as 100’ by 100’. It all depends on who owns the property and if they are willing to sell lots that are that big. Although the average is 20’ by 40’, that’s by no means written in stone as the most common lot size you will find in the whole country.

If you own a Class A RV, you may want something that is significantly larger than what is considered to be average. You may need a lot that is large enough that you can do some gardening or add on a large patio or deck.

Some RV lots are large enough that the owners build privacy fences. Whatever size lot you need, there is liable to be something out there that fits your parameters.

Final thoughts

RV lots come in all shapes and sizes, though the most common size is rectangular. They average 40’ in length and 20’ in width, though you will hear others claim differently. The fact of the matter is, no matter what RV lot you’re seeking or what size your RV is, there is something in every state that will accommodate your needs.
