Methodology

Last updated October 27, 2026

What the score is

Each brand report card shows a score from A to F that is calculated from published facts: NHTSA recall filings, the maker's own warranty terms, advertised prices from public listings, and what the maker publishes about itself on its own website. Nobody grades by opinion, and each category shows the fact it uses so you can check it. The same method is used for every brand. The score describes those facts. It is not a safety rating, an inspection, or a statement about any single trailer.

The five graded categories and their weights

How each category is graded

Recall record

We count NHTSA recall campaigns received in the last five years that name the brand's trailers. 0 campaigns is an A, 1 to 2 is a B, 3 to 4 is a C, 5 to 6 is a D, and 7 or more is an F. Campaigns about motorcoaches, motor homes, RVs, or travel trailers filed under the same maker name are not counted, and each brand page lists what was left out. A campaign that names several brands counts for each brand named, including a campaign filed under a parent maker's name when it names the brand's trailers. Recalls of aftermarket living quarters conversions are not counted against trailer makers. The count is not weighted by severity and is not adjusted for how many trailers a brand builds. A recall is a safety campaign filed by a maker. It is not a finding that anyone did something wrong.

Warranty

We take the structure or frame warranty term the maker publishes. Where terms differ by model line, we grade the term on the maker's main line, the most common one in its lineup, and the report card lists the other lines for reference. We leave out commercial use terms. A limited lifetime frame warranty counts as 10 years. 8 years or more is an A, 5 to 7 is a B, 3 to 4 is a C, 2 is a D, and under 2 is an F. If we did not find a structure or frame term on the maker's own pages we reviewed, Warranty is Not rated.

Resale value

For the same brand, trailer type, and GVWR class, we divide the used median advertised price by the new median advertised price, weighted by the number of used listings. 85 percent or more is an A, 75 to 84 is a B, 65 to 74 is a C, 55 to 64 is a D, and under 55 is an F. We need at least 5 listings from at least 2 sellers in each new and used group, and at least 10 used listings in total. A ratio above 110 percent means the new and used listings are not comparable, so the category is Not rated. These are asking prices, not sale prices, and they do not adjust for age or condition.

Price position

We compare the brand's new median advertised price with the median of the other brands in the same trailer type and GVWR class, weighted by listings. Living quarters horse and stock trailers are compared only with other living quarters trailers, apart from standard ones. Each group needs at least 5 listings from at least 2 sellers, at least 3 other brands, and the brand needs at least 10 listings in total. At 90 percent of that median or lower is an A, 91 to 97 is a B, 98 to 105 is a C, 106 to 115 is a D, and above 115 is an F. This measures cost to the buyer, not quality, which is why it carries a low weight.

Spec transparency

Four items, one point each, when the maker publishes them on its own website: headquarters and plant location, the full warranty document, a spec sheet with GVWR, and owner manual or recall contact information. 4 points is an A, 3 is a B, 2 is a C, 1 is a D, and 0 is an F. A brand is graded here only when we read 25 or more of the maker's own pages. If we read fewer than 25, or could not read the maker's site, Spec transparency shows Not rated. That is not a low grade and it is not a statement about the maker. When an item shows as not published, it means we did not find it on the maker's own pages we reviewed. It does not mean the maker lacks it, because it may sit in a brochure, an image, or a page we did not read.

Build specs are facts, not grades

Each report card also shows build facts for every model line where the maker lists specs: frame type and material, axle brand, axle or suspension warranty stated by the maker, brake type and axles braked, wiring and lights, and deck or floor material and thickness. These facts do not change any grade. We keep them out of the grade because a spec that is missing from the text of a maker's web page would lower a grade because of how a website is laid out, not because of the trailer. When a model page does not show an item, the card says it is not listed on the model pages we read. That does not mean the trailer lacks the feature.

The overall score

Each rated category earns points: A is 4, B is 3, C is 2, D is 1, and F is 0. The overall score is the average of those points, weighted by the category weights above, using only the categories that are rated. 3.5 or more is an A, 2.5 to 3.49 is a B, 1.5 to 2.49 is a C, 0.5 to 1.49 is a D, and under 0.5 is an F. Each report card shows how many of the five categories the score is based on, and a grade based on only 3 categories is labeled Limited data.

Not rated and not enough published facts

If we do not have the facts or enough listings for a category, it shows Not rated and does not count toward the score. A brand gets an overall score only when at least 3 categories are rated and the rated categories carry at least 55 of the 100 weight points. Otherwise the card shows Not enough published facts. That is not a low grade. It means we do not yet have enough published facts to grade the brand fairly.

Where the facts come from

Recalls come from NHTSA, and every campaign shown has its NHTSA campaign number and a link. Summaries are quoted as the maker filed them. Warranty, frame, axle, and headquarters facts come from the maker's own published pages and are linked on each report card. In a few cases the maker's policy text is posted on a dealer's page, and the report card says so until we confirm it with the maker. Prices come from public dealer and classified listings, using the middle 80 percent of advertised prices. Our matching can miss campaigns filed under other names, and makers can change their terms at any time. Check any trailer's VIN at nhtsa.gov/recalls.

Grades are never for sale

We do not take money for grades. Dealers can pay to list trailers and sponsors can pay to be shown, always labeled Sponsored, and nobody can pay to change a score or to leave one out. A score describes a brand's published facts, not the trailer you are looking at.

Featured trailers. The Featured trailers row on the home page is paid placement by approved dealers, and every card in it is labeled Featured. Paid placement. Featured spots never affect grades. Until dealers fill the spots, the row shows sample trailers from Springpoint Trailer Sales, and the row says so.

Who owns TrailerGrade

TrailerGrade's founder owns Springpoint Trailer Sales in Newton, Illinois. As of October 26, 2026, Springpoint currently sells new Liberty, Doolittle, and Platinum trailers, and its listings on this site may also include other brands taken in on trade or sold used. Scores are calculated from published facts by the same method for every brand, with no extra weight for those three. The report cards for Liberty, Doolittle, and Platinum carry this disclosure. See Disclosures.
