Rear Trailer Overhang

We have a drive that has a moderate slope which was close to hitting the rear of our old 1970 25ft LandYacht. We no longer have that trailer and are looking for a replacement and wondered if a 27, 28 or 29ft would be too long to back into our drive.

Is there someone out there that knows the overhang (center of rear axle to back bumper) on the 25, 27, 28 and 29's?

I called Airstream and was told they don't have dimensional drawings.

Thanks in advance...

Orin

Don't forget that axle condition and tow vehicle wheelbase and rear overhang will affect the likelyhood of problems, as well.

Our 1971 25' measures 88" from rear axle centerline to rear bumper, if that helps.

Hi Bart,

Thank you very much for sending your measurement - That will really help!! I'm starting to think that, without a lot of work, a 27 may be the longest we can back up the slope..... but I sure would like to have a 29 -

Airstream surely has the drawings. But Barts is correct, it is not that simple. The only way to tell for sure is to buy the trailer and then back it into your driveway. If it rubs the driveway when you back it up, figure out what you need to do to avoid it rubbing the driveway (like lowering the level of the ball, etc.).

Good luck, Dan

Hi Dan,

Yes, I would have thought I could have gotten a drawing from their "service" department but the guy I spoke to said they didn't have one he could send. Guess he was too busy......

Your suggestion to buy the trailer and try it simply isn't an option. The work I mentioned would involve regrading my concrete drive and that just isn't a reasonable option.

How low can you go?

Why not mount a front hitch on your truck and use a drop bar to lower the Airstream hitch and raise the ass end of the trailer? Yup, it's a bit more of a hassle getting in and out of the driveway - but you can get the 29' that way.

I just measured my 27' and from the center of the rear axle to the end of the frame I see 105". I had a very similar concern when we bought this trailer as the apron on my drive slopes to the gutter more than most of my neighbors and there is a noticeable crown to the street. My previous SOB was roughly the same length but the frame sat higher off the ground and it barely cleared the concrete when backing in. I was certain the lower Airstream would certainly drag bottom when I brought it home and knew that adding casters to the Airstream frame was a definite no-no. I was prepared to unlatch the WD bars to drop the nose if necessary and considered going to 16" wheels if they would have helped, but was absolutely amazed that it never touches bottom. Ironically, if I had unlatched the bars the ball mount would have likely dug in. It also helps that the drive is wide enough to allow me to initially attack it at about 45° and I believe that helps the potential clearance issue. I've also noted that the angle on the apron is such that the front axle lifts clear of the pavement for about 18" while backing before those tires start turning again. I've checked the torsion arms per Andy's document and they appear to be in good shape, but hope these brief moments of overload on the rear axle doesn't take its toll over time.

That works well for us ... we even use a short wheelbase vehicle with beefed up suspension to make the job really easy!

I did not explain myself very well. I agree that regrading your driveway is not an option. I was talking about doing what Barts suggested. I believe that there is a solution to getting the Airstream that you want up the driveway without rubbing the bumper.

I forget where it was but there was a ferry where trailers had the same problem. The ferry carried a few 2 bys and strategically placing them would get the rear over the low spot.

I know these guys take their trailer on the Washington state ferry system, which has varying angles on the ferry terminal ramps. Just 5 More Minutes
They use caster wheels off the rear bumper.
Perhaps an option...

Usually you can just remove the torsion bars before you back in and that will lower the back of the tow vehicle enough to let the back end of the Airstream clear. It should at least make up the difference between the 25 & 29.

Hi Guys -

Thanks for all of the tips and suggestions!! Maybe a combination of removing the torsion (spring) bars and adding casters will solve the problem I have. That being said, we may have found a 25' which will do away with the problem. I've also found a 1987 29' Sovereign but I don't know if I want to get a trailer that old.
