Which side is typically heaviest?

I'm not sure where to stick this question. Out of curiosity for battery placement, does anyone know which side of the Airstream is typically heaviest?

I have a 27ft fb with twin layout.

I was almost certain when I read the title of this thread that I would see people voting or either the inside or the outside as being the heaviest.

My guess would be the side with the fridge. But you have to factor in whether that weight has been balanced with equipment and millwork on the opposite side.

And where the storage tanks are if they have anything in them., fresh water especially.

Got a 25fb. You can load the fridge up with a lot of heavy stuff (beer bottles) also the adjacent wardrobe, the shower is probably not that heavy but on the curb side you have the kitchen and bath and all the cabinetry and walls plus stove, sink pots and pans and the overhead cabinetry. I'm guessing when unloaded the curb side is heavier but when you load up the fridge and wardrobe it may start to equal out.

I guess you could try driving on a CAT scale with only one side of the trailer on the scales each pass if they allow it.

Our 2013 25FB and 2014 Classic share(d) the curb side rear tire having the heaviest load of the four tires by about 200 pounds when loaded for camping with full fresh water and propane tanks.

I have not had a chance to weight the 23D on my individual scales.

Assuming your total weight (on wheels) is about 8,000 lbs, that's only 10% off of perfect balance. Not bad.

I know for fact that our 2014 Classic FB unit is 90kg or 200 lb heavier on the curb side. I have also verified that the hitch weight of 540 kg or 1190 lb is unchanged whether the fresh water tank is empty or full.

My hitch weight was measured at 960lbs and I'm about to remove the two 12v batteries from the front. Already don't have the spare tire up front. Thanks.

I can't find the post, but I did see someone mention that they had gotten side-to-side weights done at JC. Their trailer was a 25FB or 27FB as I recall. They got it weighed when they brought it to JC for some service, and JC also pulled up records from when it was manufactured. Both sets of numbers were heavier on the street side.

I have an Equalizer hitch for our 25 foot International.

On a level surface and sliding the equalizer bars over, the "curb side" needs more effort to slide over than the right side of the trailer.

So, I do find that there is a difference in weight distribution. The rear bed has storage under it. Tools in the front side opening holds plenty. Refrigerator... when freshly stocked is more weight. ALL on the curb side.

Maybe Airstream had several people taking a shower to distribute weight on its engineering study. If I am forced to think this over... an empty 25 footer is probably well balanced. The engineers forgot that most Airstream owners will put stuff into these areas.

Not the first time engineers were confused. Some used metric and US for landing a space vehicle on another planet. (Some of you will recall this fact.. to Mars.) It put the landing spot some feet below the Martian surface that time.

Maybe Boldaventure is onto something. The trailers are balanced when EMPTY. It just needed one giant leap for mankind to figure out that they only remain balanced... while unsold while sitting at the local RV Sales parking lot.

All travel trailers are going to be off from one side to another.

What you need is the weight at each wheel, not each axle (to answer the question).

How important it will be is another thing. If you're running tandem axle trailer tires at max sidewall recommended pressure it won't matter much. (Front to rear changes in the trailer affecting TW percentage matter more than side to side; overall)

Use the scale with hitch both tensioned and untensioned to be accurate.

It's the load changes on the TV which matter as to best tire pressures. (Covers handling difficulties assuming no gross discrepancies with TT).

Thanks. So 100 lbs left or right won't matter match.

My last weigh in was 600lbs heavier on curb side. I want to shift some of that weight, but not sure yet how yet, far more storage on that side. Still 400lbs under max weight for that side, but I don't have a per-tire weight. Simply shifting 100lbs would reduce the difference to 400lbs, that would make me feel better. Might offset part of that by draining the hot water tank when on the move.
