Post Driveway: Backing up 27' International FB

Hi There,

I couldn't figure out the maximum grade / clearance I could expect for safely backing up AS TT based on previous forum posts. We are planning to order a 2021 International 27 FB, and wanted to know (in advance of ordering) whether the trailer would make it up our driveway.

Using some string, eyeballs and measuring tape, I figured that our driveway slope is no greater than 7% (4'6" rise over 63').

Does anyone have any idea is this is well within limits? I think that I may have seen that a 10% grade is acceptable.

Alternatively, if someone can provide me with: 1) rear clearance height of 27 FB rear bumper and 2) distance from rearmost wheel to the rear of the Airstream, I think I can figure out the geometry my self.

Many thanks in advance!

The mid sized airstreams can negotiate a 14% increase in grade change (a swale or driveway that goes up from the street) and an 8% decrease (ridge/high spot) without scraping. On swales, the spare tire holder on the front will scrape and the bumper skids on the rear. A WD hitch will protect the tire holder to 16% but will sacrifice the bumper skids at 11%. On ridges the tank pan will scrape.

Hope this helps.

If that does not give you the clearance you need you can add a lift kit. Works for me and others on the forum. Also helps with clearance issues in service stations.

Dealer installed lift kit

Ask your dealer if they are willing to install the Dexter Lift Kit on your trailer before delivery. It is now approved by Airstream and does not effect warranty. Some dealers will not install lift kit.

We have a 2019 FC 25 RBT and a steep driveway made worse by a swale at the bottom. We keep our Airstream at our house with full hookups so it was important to be able to go up driveway. My selling dealer, Out of Doors Mart, would not install lift kit. They were kind of incensed that I asked. So, I ordered kit ahead of delivery and installed myself before trying to go up driveway. Not a real difficult install if you are used to turning wrenches. It did take me all day to accomplish since it was my first install. I could cut a few hours off if I do it again.

Cost to install at the dealer should be around $1k. Congrats on your new Airstream.

Good comments above. Only other observation is if you have a steep driveway upsweep off a downsloping street, you need to be careful in three places: Under rear of trailer, under tongue jack, and if the back of your tow vehicle is vertical (like an Expedition or Suburban, or truck with rack or shell) that the 'v' created by the back of the TV and front of the trailer doesn't touch. If it does, you can bridge with boards.

Thanks very much for the advice. Dealer does not install lift kit - so that is something that I’ll add to my list of to dos.
