Trailer vs 5th wheel total length?

[DumOleBob]

we have a 23' travel trailer towed by a Ram 3500. I'm not sure with the total length is, but I am wondering how much 5th wheel could I get that would keep the total length within the size of the tt and truck? Is there any "rule of thumb" for comparable length?

Usuallt the model tells you the inside length of the unit, but this isn't a stead fast rule, so the best thing to do is measure your trailer now, then measure from the hitch ball to the center of your rear axle on the truck. add the two together and that will be the outside length of a fifth wheel that will give you the same overall length.

There is no rule of thumb to compare lengths. Just meausure from the hitch ball to the center of your rear axle. That is how much more fifth wheel length you can get to make the entire rig the same length as it is now.

It depends if in your trailer length you are counting the 3 foot 'A' frame that holds the propane and battery. You can add that 3 feet also.

Thanks! I was thinking it more complicated than it is...!
