5th wheel lengths (model# vs reality)

I see a lot of manufacturers name their models based on lengths that are much shorter than the true overall length. I can see rounding to the nearest foot but in many cases the model number will represent a length that is 3ft or more shorter than actual overall length. Why do they do this, and what are they basing the advertised (model number) length off of?

the model no. doesn't count the closet space in the front of the camper. My Keystone copper Canyon model was 293 which you would be 29 ft. was 32 ft from pin to rear bumper

The Titanium fivers from Glendale of Canada (now bankrupt) have five additional feet of bedroom space hung out over the cab of the tow vehicle.

The model numbers indicate this: 24-E-29, 30-E-35; 37-E-42, etc. (Usually written without the dashes "30E35"). The first number is the approximate length from pin to rear bumper and the second it the length of the living area. The letters after the extended length are to designate interior arrangements. In my case 30E35SA shows a "side aisle" bathroom layout.

Cummins,it is not bragging or showing off if stating a fact...ok maybe just a little, but i really do use the 20 ft. garage. :B

I figure the height this way. I stay away from anything less(posted) than the 13'6" heights needed for semis. I just keep an eye out for low branches on county roads and in campgrounds as they are not marked.:)

My current rig is a 36TKSB3. Which means it is a 36 foot unit, it actually measures 36 feet 11 inches. Our former 36 foot HH Champagne measured 37 feet 4 inches. So in these cases the trailers are larger than the unit designation.
Hope this helps.

I looked at the brochure for mine and the outside listed length is correct but in reality it is off by more than a foot because it doesn't include the rear bumper and then the ladder sticks out further. If you got a place that limits length for a site you may have to ask if they include just the shell or the also the bumper and ladder if you are close. My is a 5th wheel so I didn't figure on a tongue. But in reality is I were to include the 5th hitch as well it sticks out the front a bit so that would be even more of a problem depending on what the place measures for limiting. Generally I see this at state parks in maine.

Not a guaranteed height, but one easy way found is next time you are under an canopy at a gas station that you can reach from your roof, measure down from the canopy to your high point, then measure down from the canopy to the ground.

Just know that when maneuvering under a canopy or pulling into a garage, a change in grade can cause the truck to go down in the front and push your pin up. If AC or something on roof toward the front is the high point, it can raise a few more inches than what it was level.

OK, years ago, the number did generally mean something, and it generally was the overall length. We had a Fleetwood Prowler 24M, was 24' from hitch to bumper with 21' actual inside space. Our next TT a Gulfstream Conquest was a 26XXX (forget the letters), but was actually 26' box, making for approx 30' overall.
2010 Montana 2955RL (same model posted earlier at 32') ours was 34'. Now current Redwood is a 36RL, brochure length of 38'11", but it's measured from the King Pin back, actual spec drawing length is 40'2" tip to tail and 409 SqFt.
Oh, in reference to an earlier post that model numbers told you which model is bigger, not always the case as with Montana, 3400/3402 are one of the bigger models, yet many smaller have higher model numbers.
So in the End, as has been said many times, get out the trusty tape measure and get to the scales, only way to know for sure.............


Still find it hard to believe that the manufacturer doesn't post exterior lengths, ie from as far out front as the 5er extends, whether it be the pin or the front cap, to the very end, be it a bumper, spare tire or the ladder....used to be they did it all the time, and again, if one checked it with their trusty tape measure, would find it within an inch or two of actual front to back measure...unless some don't understand what exterior length includes.

also if one add's a bike rack or a carrier to the back of their 5er or TT, they need to add that additional length to the unit...

I believe it's already been established that the numbers may or may not mean much of anything...all I was recommending, in the scheme of things, "IF" one doesn't have a tape on them and they're trying to figure out length of the unit, (which WAS original topic), 99% the exterior length is listed in the manufacturers brochure that should be found at the dealership....if it's an older unit....carry your tape measure around with you, (I keep a 50' tape measure in my trucks tool box)..

I read, (not all posts) most posts, and in talking about measuring height, no one really said when loaded on the TV.


Good point, because if it's setting level, doesn't mean it'll be setting level when hooked to one's truck when towing....I've done it both way's and when hooked to my truck, while setting on level ground, the unit is taller than when measured setting on level ground and unit has been leveled...very good point.
