Does the Texas lemon law cover RVs and boats?
RVs, yes. The statute's "motor vehicle" definition expressly includes "a towable recreational vehicle" (Tex. Occ. Code § 2301.002(23)(D)), and a motor home is defined as a motor vehicle with temporary living quarters (§ 2301.002(32)). TxDMV's covered list names both: "motor homes, towable recreational vehicles (TRVs)".
Boats, no. The statutory definition does not include vessels, and TxDMV states plainly: "The law does not cover repossessed vehicles, non-travel trailers, boats, or farm equipment." Note the middle item: a plain boat trailer does not meet the towable-RV definition quoted below (it provides no temporary human habitation), which leaves it among the excluded non-travel trailers even though it rolls on the highway.
Does Texas have a lemon law for RVs?
Yes, the same one that covers cars: there is no separate RV statute, and no separate RV agency. A qualifying motor home or TRV runs through the same TxDMV complaint process, the same repair-attempt presumptions, and the same remedies as any other new motor vehicle; the new-vehicles page has those tests with their citations. What makes a TRV a TRV is itself defined:
'Towable recreational vehicle' means a nonmotorized vehicle that: (A) was originally designed and manufactured primarily to provide temporary human habitation in conjunction with recreational, camping, or seasonal use; (B) meets the requirements to be issued a certificate of title and registration by the department as a travel trailer through a county tax assessor-collector; (C) is permanently built on a single chassis; (D) contains at least one life support system; and (E) is designed to be towable by a motor vehicle.
The filing deadline runs six months from the earliest of warranty expiration, 24 months, or 24,000 miles from original delivery (§ 2301.606(d)). On its program page, TxDMV prints that mileage trigger with the parenthetical "(except TRVs)". The statute's own deadline text contains no TRV exception. We publish both statements, each attributed to its source, because they differ and an RV owner deciding when to file should know that they do. Confirm your own filing window with TxDMV or a licensed attorney rather than resolving the difference yourself.
If a towable RV is bought back, the clock is days, not miles
When a repurchase is ordered, the refund is reduced by an allowance for the use you got out of the vehicle. For an ordinary motor vehicle the rules measure that against a presumed useful life of 120,000 miles. A towable recreational vehicle is measured differently, and if you have only ever read the mileage version you will estimate your own case wrong: its presumed useful life is 5,475 days, or 15 years, and the allowance is computed from days of ownership rather than distance travelled.
Two things follow that are worth knowing. The presumption is rebuttable in either direction, so evidence that a particular trailer has a longer or shorter life than 15 years can move it. And days the vehicle spent out of service being repaired come out of the calculation, which matters most to exactly the owner who ends up in this proceeding.
There is a rebuttable presumption the expected useful life of a towable recreational vehicle is 5,475 days or 15 years. ... Any day or part of a day that the vehicle is out of service for repair will be deducted from the numerator in determining the reasonable allowance for use of a towable recreational vehicle in this paragraph.
This page states the presumption and the rule that carries it. It does not compute your allowance, and no page on this site will: the rule's own arithmetic depends on dates and figures specific to your purchase, and a number produced here would be an estimate dressed as an entitlement.
Whose warranty is it when the chassis and the house have different makers?
Where a motor home's chassis comes from one manufacturer and its living quarters are built onto it by another, an owner facing a defect wants to know which of them the state will hold responsible. The honest answer is that the hearing rules do not resolve it. Subchapter G does not say. It directs relief at "the manufacturer, distributor, or converter" as a single category throughout, and it never uses the words chassis, house, motor home, or warrantor at all. Both of this site's independent readings went looking for an allocation rule and neither found one.
the hearings examiner shall issue a final order to the manufacturer, distributor, or converter to: (A) replace the motor vehicle with a comparable motor vehicle; or (B) accept the return of the motor vehicle from the owner and refund the full purchase price of the motor vehicle to the owner, less a reasonable allowance for the owner's use of the motor vehicle and any other allowances or refunds payable to the owner.
It means the hearing rules contain no chassis-versus-house allocation rule. It does not mean the question has no answer: your own warranty documents, the terms of each manufacturer's express warranty, and the statute's definitions are all elsewhere, and this site has not verified how they interact for a two-manufacturer RV. We are telling you where we looked and what was not there, rather than filling the gap with a guess. If a defect sits on the boundary between chassis and coach, that is a question for a licensed attorney with both warranties in front of them.
Boats: a different agency, and a different answer
Texas titles and registers vessels through the Texas Parks and Wildlife Department, not TxDMV, and the lemon law does not reach them: boats appear nowhere in the statute's "motor vehicle" definition, and the agency's own page says so outright. That does not mean a defective new boat has no remedy under any law; it means the remedy, if there is one, does not run through the TxDMV lemon law program this guide covers.
The one body of law this site can point to with a verified scope is the federal Magnuson-Moss Warranty Act, which governs written warranties on "consumer products", defined in its own text as tangible personal property "normally used for personal, family, or household purposes". Its official text is linked in the sidebar so you can read its scope provisions yourself; whether it reaches any particular boat dispute is a question about that dispute, and this site does not evaluate cases.
