RV auction fees and the buyer premium

By the RVBidFind research team · Updated September 7, 2026 · 5 min read

The number on the bid button is never the number on the invoice. Here is every fee that stacks on an auction RV, what each kind of platform typically charges, and how to turn a comp value into a max bid that survives them.

The buyer premium

A percentage added to the hammer price, set by the auction house, not by the bidder. Commercial platforms — Proxibid, BidSpotter, the repo specialists, most regional houses — typically charge 10 to 15 percent, sometimes tiered so the rate falls as the price rises, and sometimes with an extra internet-bidding surcharge. Copart broker sales stack a broker fee on top of the yard's own tiered fees and a gate fee. eBay Motors charges the buyer no premium on vehicles. State and federal surplus programs usually charge none at all, though some counties add a small administrative fee.

That gap is why a $9,000 surplus motorhome and a $9,000 consignment motorhome are not the same price. Every source page on RVBidFind lists the typical premium for that house, and the all-in figure on each lot uses it; the lot terms on the auction site always govern.

Sales tax

Sales or use tax is generally charged at registration in your home state on the purchase price, regardless of where the auction was held. Some states tax the hammer price only; some include the premium; a few states charge no sales tax on vehicles. Trade-in credit does not apply to an auction purchase. If the auction house collects tax at the sale because you are a resident of its state, keep the receipt — your DMV will credit it. Taxes and registration after you win goes deeper.

Documentation and handling fees

A flat documentation or title fee of roughly $50 to $300 is common on commercial platforms. Repo houses sometimes add a handling or loading fee, and yards charge a gate fee when a hauler collects. Surplus sites occasionally charge a small administrative fee. None of these are large on their own; together they are a few hundred dollars that belong in the max bid.

Transport

The fee people forget, and often the largest after the premium. A non-running coach needs a flatbed or lowboy; a running one still needs fuel, a driver and possibly a one-way flight; a towable needs a truck rated for it. Budget on the order of $2 to $3 a mile for a hauler, less for a towable behind your own vehicle. RVBidFind's all-in figure uses 250 miles by default, or the approximate distance from your ZIP when you enter one; set your own on the lot page. Transport costs and haulers covers the options.

Storage and late fees

Most houses give five to ten days to collect. After that, daily storage fees start, and an unpaid lot is re-listed with the deposit forfeited and, at many houses, the bidder banned. Line up transport before you bid, not after you win.

How the fee stack differs by kind of sale

The same $10,000 hammer lands very differently depending on who is selling. At a repo house expect roughly 10 to 13 percent premium plus a documentation fee, with the title handed over at pickup. On a marketplace such as Proxibid the premium is set by each consigning auctioneer and can run higher, with an internet surcharge on top; read the specific auction's terms, not the platform's home page. At a Copart broker the yard's tiered buyer fee, a gate fee and the broker's own fee stack together, and daily storage begins within a few days of the sale. On state and federal surplus sites there is usually no premium, but there may be a small administrative fee and a hard pickup deadline. On eBay Motors the buyer pays no premium on vehicles, but a dealer seller may add a documentation fee and the deposit is due at auction end.

RVBidFind's auction sites pages list the typical premium for each house, and the all-in figure on every lot already uses it. When the lot terms disagree with the estimate, the lot terms win.

Reconditioning: the fee you charge yourself

Auction rigs are not retail-ready. Tires by date, batteries, fluids, roof sealant, a water system test and whatever the disclosed damage flags imply. RVBidFind adds a reconditioning allowance to every all-in estimate — a percentage of value with a floor, plus more for non-running, flood, fire or salvage flags. Treat it as a fee, because your bank account will.

Working back to a max bid

Start with what the rig is worth to you — the comp value is the market's answer, and the retail reference is what you could sell it for with patience — and subtract in this order: the margin you want to keep, transport, documentation fee, reconditioning, then sales tax, then divide out the buyer premium. What is left is the most you can bid and still come out ahead. Members see this as max bid on every lot; what RVs cost at auction shows the ranges the calculation starts from.

A worked example: a rig worth $14,000 to you, a 13 percent premium, 6 percent tax, a $150 doc fee, $500 of transport and $700 of reconditioning. Subtract the fixed costs ($1,350) to get $12,650, then divide by 1.13 × 1.06 ≈ 1.198 to get a max bid of about $10,550. Bidding $12,000 because it “comps at $14,000” loses money.
