How Online RV Auctions Work: Proxy Bids, Soft Close, Reserves and Fees

By the RVBidFind research team · Updated September 7, 2026 · 6 min read

Online RV auctions work like this: you register on the auction site, enter the most you are willing to pay, and the software raises your bid one increment at a time against other bidders until the lot closes. The winner pays the hammer price plus a buyer premium, tax and fees, then has a few days to pay and pick up. The details, timed or live closes, soft-close extensions, reserves and deposits, decide what you actually pay and whether you get the unit at all. Here is each step so your first bid is a deliberate one.

Timed Online Auctions vs. Live and Simulcast Sales

A timed online auction opens bidding days or weeks ahead and closes each lot at a scheduled time, with no auctioneer. Bank-repo remarketers like CrankyApe, Repocast and Orbitbid and most government surplus sites run this way.

A live or simulcast auction is a traditional auctioneer-run sale with an internet feed. You bid in real time against the room and other online bidders, and lots often move in under a minute. Proxibid and BidSpotter host many of these. Live sales reward preparation: know your number before the lot comes up.

Proxy Bidding: How a Max Bid Actually Works

Nearly every platform uses proxy bidding, also called max or absentee bidding. You enter the most you will pay and the system bids for you, one increment at a time, only as high as needed to stay ahead. If you enter $18,000 on a lot sitting at $12,500, the system bids one increment over the current high bidder's hidden max, and if nobody else bids again you win there, not at $18,000. If the other bidder's max really was $12,500, you pay $12,500 plus one increment.

Your max is hidden from other bidders. Whether the auction house or seller can see it varies by platform, so read the bidder terms before entering a number you would not want them to know. If two bidders enter the same max, the earlier bid usually wins the tie, so bidding early with a real max is not a disadvantage.

Bid Increments and Why the Price Jumps

Most sites publish an increment table that scales with price: a lot under a few thousand dollars might move in $25 or $50 steps, while a $40,000 motorhome may move in $250 or $500 steps. Tables vary by site, so check the lot terms.

If the increment at your level is $500 and your max is $20,200, some platforms will never use the last $200. Set your ceiling on an increment boundary, and remember that the final price lands one increment above the second-highest bidder's max, or at your max if that increment would carry past it, so it rarely lands exactly on your number.

Soft Close and Extended Bidding

A hard close ends at the posted time no matter what, which invites sniping, a bid dropped in the last seconds. eBay Motors closes this way.

Most repo remarketers and many surplus sites use a soft close, also called extended bidding or anti-snipe. Any bid in the final few minutes resets the clock, and the lot does not close until that window passes with no new bids. Lots can run well past schedule.

Under a soft close, waiting gains nothing: enter your true max and let the software work. Under a hard close, a proxy max placed early still answers late snipers up to your limit.

Reserve vs. No-Reserve, and What "Reserve Not Met" Means

A reserve is the confidential minimum a seller will accept. If bidding ends below it, the lot does not sell automatically, and many sites flag it as "reserve not met" or "subject to seller confirmation." The seller may then accept the high bid, send a counteroffer, or relist. If that is you, watch your email for a few days, but do not count on a deal, and be aware that on many sites your bid stays open as a binding offer during that window; check the lot terms.

A no-reserve or absolute lot sells to the highest bidder regardless of price. Many government surplus sales and some repo sales run this way, and that is where the deepest discounts show up. An opening bid on an absolute lot is not a reserve. Our repo auction guide explains how lender sales handle reserves.

Buyer Premiums, Internet Surcharges and the Real Total

The hammer price is not what you pay. Commercial platforms add a buyer premium, typically 10 to 15 percent of the winning bid. eBay charges none on vehicles, and most state and federal surplus programs charge none. Some live auctions also add an internet surcharge for bidding online rather than on the floor; read the terms before you register.

Then come sales tax (varies by state and delivery location), a documentation or title fee, and transport, which climbs quickly on a unit that cannot be driven. RVBidFind's all-in estimate adds premium, sales tax, a documentation fee, transport at about $2.25 per mile and a reconditioning allowance. Full details are in our guide to auction fees and buyer premiums.

Registration, Deposits and ID Checks

You cannot bid as a guest: expect to create an account, verify a phone or email, and put a card on file. Many sites place a temporary card hold or require a refundable deposit before your first bid, larger for high-value lots. Most bank-repo remarketers and most surplus sites are open to the public, though a few remarketers, including some powersports auctions, sell to licensed dealers only. Copart and IAA lots are often restricted to licensed dealers, though rules vary by state, which is why brokers like A Better Bid and AutoBidMaster bid on your behalf for their own fee; see salvage RV auctions for how that route works.

Some platforms want a driver's license scan before releasing a title, and approval is not always instant, so register a day or two before the lot closes.

Payment Deadlines, Pickup and Non-Paying Bidders

Winning is a contract. Most sites require full payment within a few business days by wire transfer, cashier's check or, sometimes, credit card with a limit or fee. Pickup deadlines follow, often within a week or two, then storage fees accrue; check the lot terms.

If you do not pay, expect to lose your deposit and your account on that platform. Many houses also charge the card on file the buyer premium or a fixed penalty, and some reserve the right to pursue the difference if the lot resells for less. Never bid on a lot you cannot pay for and move on time.

Buy-It-Now Prices and Holding Your Number

Some lots carry a fixed buy-it-now price alongside the auction. On eBay it usually disappears once bidding starts; elsewhere it may stay until the lot closes. It can make sense at or under your all-in number but is rarely the cheapest route.

The hardest part of online bidding is not the software. It is holding your number when someone outbids you by one increment with two minutes left. Set that number before you look at the current bid: start from what comparable rigs have actually sold for, subtract premium, tax, transport and a repair cushion, and round down to an increment. Hammer prices commonly land 30 to 50 percent under dealer asking for the same year and model, so there is no need to chase.

Pro members see comp value, deal score, all-in cost and max bid on lots with enough comparable sales to value them. Start on the search page and read the full buying walkthrough before you bid.
