Your total length, truck and trailer

Hi all,

I may have found an opportunity on a fifth wheel and I’m waiting on the specs, but I believe it’s going to be a 40 foot long Montana.

Right now, hooked to my travel trailer, I know my truck is 22’ long and I have a foot more for the wd hitch, then my current travel trailer is 28’ long from coupler to spare tire. I can safely figure that I am 51 feet long overall when hitched.

I’ve tried searching every way I can think and I’m not coming up with a solid answer for myself. I figured (and am probably wrong) that about three feet of the fifth wheel length will be in the bed of my truck, then about three feet of my truck will be under the fifth wheel. So if I take six feet away from the truck and the trailer, I’m coming up with about 56 feet long overall when hitched. Does this sound about right?

Does anyone with a crew cab long bed truck know what they’re overall length is with their 40 foot fifth wheel hitched? Anyone possibly with a (within five year old) Montana?

    You measure from the back bumper of the trailer to the pin, than add the distance from the truck rear axle to the front bumper. My trailer is 38 ft total rig s 55.

    We have a long box RAM 3500, our trailer is 39’ 8”. I can’t remember the exact dimension of my truck (sorry) but our over all length is right at 57”, might be 57’ 3” but it’s really close to just plain 57’. Hope this helps.

    Im running a 39.5 foot 5th on a long box crew cab and am running 56-57 feet long with the bike rack closed, 59 feet long with it open. so ya your guess is pretty close.

    Your making this too complicated. Measure your truck from front bumper to the back of the cab. Add 43 feet (40 foot of trailer plus space between cab and front of trailer) to that and you should be close.


    That is very possible. Thanks

    I'm at around 59 feet total length. You don't say why you're so concerned with overall length. Don't over think it, it's just a trailer back there. Going straight on the highway is nothing. Turning corners takes a little more thinking, just like you're doing with you're current trailer. You're first trip will show you you're concerned about nothing.
