RVs are some of the most expensive private-party vehicle sales Oklahomans handle, and because the excise tax is based on the sale price, the bill of sale price has real dollars behind it. There is no state inspection backstop, so the buyer should plan for a thorough pre-purchase walk-through covering chassis (for motorhomes), house systems (water, propane, electrical, slide-outs), roof condition, and tire age. Travel trailers and motorhomes both go through Tag Agencies with the same deadlines: pre-registration within 2 business days and title within two months. A detailed bill of sale listing included items (generators, satellite, hitches, solar) prevents arguments about what stays and what leaves.
Motorhomes title like motor vehicles; towable trailers title like trailers — and the paperwork differs for each. Our RV guide covers lien holder procedures, what to do with an active loan balance, the Montana-LLC question, and how RV registration deadlines work.

Both motorhomes and travel trailers are titled through Service Oklahoma. Federal odometer disclosure applies to motorized RVs of model year 2011 or newer; travel trailers do not have odometers. Slide-outs, levelers, and major appliances should be tested before sale.
Inspection
Not required
Sales Tax Details
Used RVs are subject to the motor vehicle excise tax on the documented sale price. On a higher-value RV that is a meaningful amount of tax.
Exemption: Some transfers between family members may be exempt from the excise tax; which relationships and paperwork qualify is not confirmed here, so check with Service Oklahoma or a licensed tag agency.
Inspection Requirements
No state safety or emissions inspection is required for RV titling or registration. Independent RV inspections by a certified RV inspector (NRVIA) are highly recommended for any unit over $20,000.
Registration
Registration for this vehicle type is handled by Oklahoma Tag Agency (private contractor offices statewide) — not the same agency that handles cars in Oklahoma. Plan for separate filings.
Oklahoma RV Sale — Step-by-Step Checklist
Verify VIN on title matches the chassis (motorhomes) or trailer frame plate
Test all systems: water pump, hot water heater, furnace, AC, fridge on shore power and propane, generator, slide-outs, levelers
Inspect the roof — soft spots, sealant condition, and seam integrity drive thousands in repair costs
Check tire age (DOT date code on sidewall) — RV tires age out before they wear out, typically 5–7 years
List included accessories explicitly: hitch, bike rack, generator, solar panels, batteries, leveling blocks
Buyer takes the signed, notarized title (or Form 718), bill of sale, and insurance to a Tag Agency within two months for the excise tax
Common Pitfalls
Skipping a roof inspection on an older motorhome — water damage repairs can hit $10,000–$20,000
Buying an RV with old tires — date codes over 7 years old mean immediate replacement before towing
Underestimating excise on a high-value RV — it is based on the sale price and due at the Tag Agency
Vague "as-shown" inventories that lead to disputes over the generator, satellite dome, or hitch
Forgetting propane tanks and recertification status — DOT cylinders need recertification every 5–12 years
Missing the two-month title deadline — the late penalty is $1 per day, up to $100
Pro Tip
Oklahoma RVs go through Tag Agencies on the same notarized-title / excise-tax / two-month playbook as cars — just with bigger dollar figures and more systems to inspect. A pre-purchase RV inspection and a detailed bill of sale are where the deals hold up.
Oklahoma RV Bill of Sale — FAQs
How is RV excise tax calculated in Oklahoma?
Used RVs are subject to Oklahoma's motor vehicle excise tax on the actual sale price (68 O.S. §2104). The buyer pays excise plus title and registration fees at the Tag Agency. On a large Class A motorhome the excise is a significant amount, so budget accordingly. The statutory basis is the actual sale price, so document it accurately.
Should I get an RV inspection before buying in Oklahoma?
Strongly recommended for any RV over $20,000. NRVIA-certified RV inspectors perform comprehensive walk-throughs — fluid analysis on motorhome engines, roof and seam inspection, all house systems on both shore power and propane, slide-out operation, water tank pressure tests, generator load test. Cost is typically $400–$900 depending on RV class and length. Oklahoma has no state RV inspection, so this is the only neutral evaluation you will get. The cost-of-inspection vs. cost-of-surprise-repair math heavily favors getting the inspection done.
Do travel trailers get titled the same way as motorhomes in Oklahoma?
Yes. Both travel trailers and motorhomes are titled at a licensed Tag Agency, both pay the excise tax on the sale price, and both follow the same deadlines: pre-registration within 2 business days and title within two months. The main differences: travel trailers have no odometer (so no federal odometer disclosure required), motorhomes do require disclosure for vehicles of model year 2011 or newer, and motorhome registration fees are typically higher because they are based on motorized vehicle schedules rather than trailer schedules. Both need a tow vehicle or self-propulsion to actually leave the seller property.
What about the propane tanks and generator on an RV sale?
List both explicitly on the bill of sale. DOT propane cylinders (typical 20–40 lb tanks on travel trailers) require recertification every 5–12 years depending on tank age and type — buyers should check the date stamp before assuming the tanks are usable. Permanently mounted ASME propane tanks (typical on motorhomes) do not require recertification but should be inspected for corrosion. Generator hours should be documented from the hour meter, and the generator should be load-tested during the walk-through. Note any recent service or maintenance records to support the listed condition.
How long do I have to title my new-to-me RV in Oklahoma?
Two months. Oklahoma requires the sale to be pre-registered within 2 business days, and the buyer to title and register at a Tag Agency within two months of the sale date. After two months the penalty is $1 per day, up to $100. You also cannot legally insure or operate the RV without registration, so getting to the Tag Agency promptly is in your interest beyond just avoiding penalties. Bring the signed-over, notarized title (or Form 718), bill of sale, proof of insurance, and a payment method covering the excise tax plus title and tag fees.
