RVers talk in code. It is the same for many different industries and you may be familiar with this setup if you use a computer and social media a lot. Just like computer geeks, RVers have developed their own coded language and it takes a while for your to get up to speed and know what someone is talking about.
There is a long list of abbreviations RVers and RV makers use to shorten their speaking and writing time. This code can get confusing and you may have to print the information out and refer to it from time to time so you can keep up with the content of what someone is saying.
To learn more about this topic, just continue to read our article. It provides a list of acronyms, abbreviations, and code letters so you know what is being referred to when they are used in a sentence. The list is quite long and some are easy to understand.
You are definitely not going to like the answer to this question. To be honest, they rarely mean anything except to the RV maker. There is no universal application or designation for these code letters and numbers.
That is the easy part of this answer. The difficult concept is that some RVs and trailers can have the same exact code but be two different trailers from two different brands. Or they are the same exact trailer from 2 different brands and have 2 different model numbers.
On it goes. There is no set standard for these model numbers. When it comes to the numbers, sometimes they refer to length and sometimes to the square footage as we will explain next.
However, sometimes those numbers are just numbers. They mean nothing except to say one trailer has a slide and one does not. The letters that follow the numbers usually refer to the features inside the trailer or RV.
For example, if you have a model number- 212RBSWE- the letters mean rear bath, slide, and western edition. Because all RV makers use their own system, you will get different model numbers meaning different things
You may hate this answer by now but it will depend on who is making the RV or trailer. For example, prior to 2008, there was a 2-number code that referred to the length of the coach or trailer. For example, if the model number said AB30, it meant that the model number was 30 feet in length.
If the model number read AB190 then that meant you had 190 square feet of RV or trailer space. However, after 2008, things became confusing. The Class A & B RV makers stick with the 2-number code while Class C RV makers will use the 3-number code.
Then the travel trailers and 5th wheel makers will use the 3-number system. This is only if the RV maker follows this system. Some may not.
The letter B can stand for bath, bed, or bunk but when it is followed by an H then those letters stand for bunkhouse. And as far as we can tell, all RV makers use those letters to mean the same thing.
Your RV or trailer will have bunk beds inside when you see the BH next to the numbers in the model number. We are going to provide you with a long list f acronyms and abbreviations later but here are some codes that relate to the beds inside an RV or trailer:
DB- dual beds- 2 queen-sized beds, FQ- front queen, K/KB- king size bed- standard, Q/QB- queen size bed- standard, TB- twin beds, MB- mid-bunk, and RQ- rear queen.
But the letter B is used quite often and when you see BG, it means bar & grill, RB is rear bath, and FB is front bath. As you can see it takes a bit to get used to these codes.
As far as we can tell and this is taken from a list from a Jayco forum, the W when by itself stands for wide or western. BUT be careful as Jayco seems to have many uses for the letter W.
WM or Wally world stands for Walmart, WD or W/D stands for washer and dryer, W/E/S = water/electric/sewer, WH is used for water heater, WWW stands for world wide web and WTNH is what the heck.
It is easy to get confused when you are new to this code game. You will see these letters and meanings on a longer list in a few minutes. There are a lot of them but get one thing straight, while we will post some letters and definitions they may only be used by Jayco and not the other RV makers.
We will provide links to other lists so you can make comparisons to see which ones are the same for everyone.
Unfortunately, we had to check several lists to get the correct meaning of these letters. The BH will stand for bunk house and the WE will stand for western edition.
The difficulty comes in when the lists do not include every possible letter code formation. BH seems to be standard across the industry as well as WE but many times they do not put the 2 together which means that those letters could also stand for bunk house, washer, and electricity.
We are not trying to confuse you any further, we just want to cover all the bases so you understand what you are reading when looking to buy a new RV or trailer.
These letters are code in RV language and not for model numbers and so on. Usually, when you read a post made by a member of an RV discussion forum you will see these from time to time these letters.
They stand for overhead cabinets. Many RVs and trailers have these inside. If you look at some other letters used in RV speak you will see OTH which means ‘on the other hand’.
The letters OK can mean that everything is alright but in RV speak it usually means outside kitchen. Be careful with OPD as it is used for two different RV components. One is the ‘overfill protection device’ and the other is the ‘overfill prevention device’.
As you can see, model codes and RV speak can get confusing at times.
Generally, this should mean bunkhouse & slide or more technically, bunkhouse with slide out. If another B is added between the H and the S, then it means bunkhouse bedroom slide out.
As far as we can tell, those letters mean the same for every RV brand you can buy. There are no other combinations using those exact same letters for different features in your RV, that we found so far.
We do encourage you to do some more research on this topic as the lists we provide do not seem to be complete and they are being added to all the time. With different RV brands using the letters for different features, do not assume you always know what those letters mean.
We did check several lists for this letter combination and none of them listed this combination. Even V or BM by itself was not listed on any of these lists. The closest we could come was VIN which stands for a vehicle identification number.
When we looked at the letters V & M, there were no stand-alone meanings for those letters. B, on the other hand (OTH), stands for bed, bunk, or bath. We keep checking as we write and it is possible that VBM should read VBN which stands for very bad news.
However, no VBM was placed on any list we were able to check.
Since most lists are a mixture of abbreviations and acronyms, we will split one list into two parts. It is a long list but before we do that, here is a link to some acronyms for all vehicles. The one for RV brands is on page 2 of this list.

We had to leave some off due to space considerations. Click on the link in the previous section to get the full list. Other lists are at this link,
You should find all that information on your purchase paperwork. It should be listed on the invoice, sales agreement, and other important documents you will need to register the vehicle.
If you have lost or misplaced that information, check the driver's side of the coach. It can be under the small window on the driver’s door, behind the front seat, or on the side of the door.
For trailers and 5th wheels, look for the model number and VIN on the driver’s side of the tongue. It may also be stamped on the pin box of a 5th-wheel trailer.
You probably thought you left school but learning never stops. Once you enter the RV world, you will have a new language to learn. The lists and links placed in this article should help you get up to speed and talk like a seasoned RVer in no time.
The only words of caution we have is to be careful. When it comes to different brands, what you think an abbreviation means for one brand may not mean the same thing for another.
When in doubt ask the other members what they mean by their use of an abbreviation.
