Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.
THE STICKER GAP IS THE NUMBER EVERYBODY ARGUES ABOUT AND IT IS NOT THE NUMBER THAT DECIDES THIS.
This is the whole page. Two trailers sit in front of you and one costs a great deal more, and that difference is real money and it is also not a cost until you say how long you are keeping it. A durability premium is bought with time. It can only be repaid in time. So the same two trailers give you opposite answers depending on a box that has nothing to do with either of them. At our defaults the Oliver lands at $80,000 against $35,000, a sticker gap of $45,000, which reads as an argument already over. Then run both across 15 years, get through two of the cheaper one because one trailer is being asked to cover a decade and a half, hand back the resale on both sides, and the Oliver comes out at $4,400 a year against $5,033. The expensive trailer is the cheaper trailer by $633 a year. Set the years to five, with one of the cheaper trailer rather than two, and it reverses hard, because you have paid the whole premium and used almost none of what it bought. Those two boxes have to move together: a replacement count that made sense across fifteen years does not make sense across five, and the page will happily compute an incoherent pair if you hand it one. Nothing about either trailer changed in either run. The division did.
The replacement count is the assumption the expensive trailer's case rests on, so we ask you rather than tell you.
The honest way to price longevity would be a service life for each trailer, and we do not have one, so this page does not print one. What it does instead is hand you the box that a service life would have filled in for you, which keeps the decision where it belongs. Be aware of how much it carries: at our defaults, changing that box from 2 to 1 moves the cheaper trailer from $5,033 a year to $3,517 and turns a $633 saving into a $883 penalty. One input, and the answer flips. That is not a weakness in the calculator, it is the actual shape of the decision, and the reason these arguments never resolve in a forum is that the two sides are quietly entering different numbers here and comparing conclusions. If you do not know your figure, run the page at 1 and at 2 and read the distance between the answers as the uncertainty you are actually carrying.
The resale percentages are yours, and between them they can decide this on their own.
Two boxes, both placeholders, both labelled as ours, and either one can carry the result. That is deliberate. Confident resale figures for these trailers are easy to find and hard to substantiate, and a number we printed would be read as a measurement and would quietly settle a decision worth tens of thousands of dollars. So we refuse to print one. What we would suggest instead is better than any average anyway: find the model you are considering, at the age you intend to sell it, and see what it is selling for now, using what buyers paid rather than what sellers asked. Do that on both sides rather than only the one you are rooting for, because the failure mode here is looking up a careful figure for the trailer you want and using folklore for the other. If the case for the premium survives your own honest numbers, it is a case made with evidence rather than with reputation, which is how this page would rather see it made.
Storage, insurance and upkeep are identical on both sides on purpose, and they move the per-year figures without moving the gap.
The rule the comparison pages on this site normally follow is to leave out anything that does not differ between the two options, because a shared line cancels out of a difference. This page breaks that rule knowingly, because it prints a per-year cost for each trailer as well as the gap, and a cost of ownership with the storage, the insurance and the upkeep missing is not a cost of ownership. Leaving it out would have shown both trailers as far cheaper to own than either is and made the premium look proportionally worse than it is. So it is in, and here is exactly what it does and does not do: it raises both per-year figures by the same amount, and it changes the gap between them by nothing at all. If you believe one of these trailers genuinely costs less to insure or maintain than the other, this page has no way to say so, and the right response is to run it twice with different carry figures and see whether that belief changes which way the gap points. Usually it will not, which is worth knowing before you argue about it.
Every one of the cheaper trailers is sold at the same percentage, which is the roughest edge in here.
If you get through two of the cheaper trailer across fifteen years, the first is sold partway and the second at the end, and in reality those two sales do not recover the same share of what was paid. This page applies one percentage to both, and that is a simplification rather than a finding. It is worth knowing which way it leans: the earlier sale is usually the one that recovers more, so a single blended percentage tends to understate what the cheaper route gets back, which is a lean toward the Oliver rather than away from it. The practical rule is the one that applies to any close comparison. If the gap this page prints is small against the numbers it is built from, the edge is inside the margin and the honest reading is that the two trailers cost about the same a year and you should choose on something other than money. If the gap is large, this edge is not what produced it.
Nothing here is discounted for time, and no finance charge is in either column. A dollar spent in year twelve is counted the same as a dollar spent today, which flatters the trailer whose spending comes later, and that is the cheaper one with a replacement in the middle of the period. If you would borrow to buy either trailer, the interest is not on this page: this is what each trailer costs, not what a loan on it costs, and the loan is larger on the expensive side. Fuel, campsites, tolls and what you eat on the road are absent from both columns too, because they follow the trips rather than the trailer, and if you want a figure that includes the using rather than the owning, the Airstream calculator on this site divides the carry by the nights you actually sleep in it.
