Cheaper on day one, or cheaper to own?
A steel trailer usually wins on sticker price. Aluminum doesn't rust, needs almost no upkeep, and holds its value — so the honest question is what it costs to own.
Purchase + upkeep − resale.

With these assumptions, over 10 years the aluminum trailer costs

despite costing $2,500 more on day one.
The chart shows what each trailer will have cost you in total if you sell it in a given year — purchase + upkeep to date − what it's still worth, with value declining evenly to your resale assumption. The shaded band is the money between the two choices.
The 10-year ledger
| Line | Aluminum | Steel |
|---|---|---|
| Purchase price | $9,000 | $6,500 |
| Upkeep × 10 years | $200 | $900 |
| Less resale value | −$6,750 | −$2,275 |
| 10-year total cost | $2,450 | $5,125 |
Every upkeep and resale figure is an assumption you control — not a promise. The formula, in full: purchase + (annual upkeep × 10) − resale. Your real costs depend on climate, storage, use, and the market when you sell.
