What Is A Big Rig RV?

In the world of RV enthusiasts, the term big rig friendly carries significant weight. It’s more than just a catchphrase; it’s a fundamental consideration that can make or break a road trip experience.

We’ve all heard the term big rig tossed around from time to time and those of us in the RV community have often heard the term big rig RV and we’ve seen RV parks and campgrounds described as having big rig access or being big rig friendly.

But what exactly constitutes a big rig RV? And what does big rig access really mean?

I’ll answer these questions and a whole lot more in today’s post all about big rig RVs. Let’s go!

What is a big rig RV?

Essentially, a big rig RV is classified as any RV over 40 feet long. Regardless of the type of RV (motorhome, fifth wheels, travel trailers) if your rig is over 40 feet long, you’ve got yourself a Big Rig.

If you have a big rig RV, you have lots of living space and you’ve also got to consider a few things owners of smaller rigs don’t have to think about like navigating city streets, your turning radius, and merging in traffic, among other issues.

You also need to carefully consider the size of your campsite and how to move in and out of it. This is why owners of large RVs search for campsites with big rig access. (You may also see the term big rig friendly used to describe campsites.)

What does big rig access mean?

Big rig access is a term used to describe the approach to a campsite that large RVs should be able to access. While a campsite may be big rig friendly and thus wide enough and long enough to accommodate your RV, if the approach to the campsite requires maneuvering through tight, narrow twists and turns around trees and large rocks, under low hanging branches, requiring masterful three-point turns to back into a site, then you’re not going to get your big rig RV into that campsite without risking damage to your rig.

So big rig access is supposed to mean that you’ll be able to approach the campsite and pull in or back in as needed, safely.

But hear me out…

Just because a campsite or RV park advertises a site or sites as having big rig access there are a couple of extra steps it makes sense to take every single time you plan your camping trip.

1. Always read reviews from other owners of large RVs who have accessed the campsite to get a sense of the reality of the situation. Again, a campground owner or marketer can measure a site and determine that adding the phrase big rig access is sensible because the site will accommodate a 43-foot diesel pusher. But if it’s tough to maneuver the rig to the campsite without risking damage to a large RV, you may not want to be there.

2. Walk to the site before driving to the site. When we arrive at a campsite, we’ll pull the rig over and walk the route we’ll have to drive to get our big rig into the site. We walk the route before we drive it (or scope it out from our easy-to-maneuver toad car). This is the best way to prevent yourself from getting into a situation that could not only damage your rig but could also be difficult to get out of once you’re in there.

What is the biggest RV size?

Generally speaking, Class A motorhomes are the largest RVs on the road though there are also very large Super C motorhomes and fifth wheels that top out between 40 and 45 feet that are most definitely big rigs!

But there are also some extremely large, custom-made big rigs out there as well.

Rumor has it that Will Smith is the proud owner of a big rig RV with 1,200 square feet of living space. That’s a pretty big rig! For reference, the rig has 14 televisions (including a 100-inch roll-down movie screen in a 30-person screening room), is two stories tall, 55 feet long, has 22 wheels, and is essentially a yacht on wheels.

But Will Smith’s 55-foot land yacht, behemoth though it is, appears small in terms of length (and only length) next to the Powerhouse Ultra Line Coach, a rig that stretches to 122 feet long with its two separate RV cabins (one towing the other).

Again, these rigs are custom-made.

But the longest Class A motorhomes on the market are 45 feet long. Manufacturers such as Newmar and Entegra make several 45-foot models. Other big forty-five-footers include bus conversions often built on Prevost chassis.

What is the biggest RV you can rent?

Why, it’s Will Smith’s rig, of course! You can rent Will’s big rig RV for a mere $9,000 a week. But, seriously, just about any length RV is available for rent via the many peer-to-peer rental platforms like RVnGo, RVshare, Outdoorsy, and RVezy. From big rig to small, they pretty much offer them all (sorry, didn’t mean to rhyme… it just happened).

Are big rig RVs considered Class A RVs?

Some custom-made RVs that are pulled by tractor-trailers are in a class all their own. But in terms of traditional RV types and classes, a typical big rig RV is most often a Class A Diesel Pusher (though, as mentioned above, there are 40+ foot fifth wheels and Super C motorhomes that also earn the title).

But, while a big rig RVs could be a Class A motorhome not all Class A motorhomes are big rigs! (There are some Class A RVs that are barely over 24 feet long.

Worth Pondering…

No matter where we go in our motorhome, that sense of independence is satisfying. We have our own facilities, from comfortable bed to a fridge full of our favorite foods. We set the thermostat the way we like it and go to bed and get up in our usual routine.
