In Q4 2025, we saw a clear expansion in small trailer activity on the Register of Approved Vehicles (RAV), with total approvals rising from 29,942 entries in Q4 2024 to 35,091 in Q4 2025. Growth was led by a handful of strongly performing domestic manufacturers and a small group of fast-emerging challengers, while the aggregated long tail of smaller brands gave up share despite adding volume. The result is a segment that is both larger and slightly more concentrated than a year earlier. Read on for our breakdown of how leading and emerging small trailer brands shaped Q4 2025 approvals.
A Note on Methodology
As with the truck trailer analysis, this report draws on Register of Approved Vehicles (RAV) entries, which capture regulatory approvals rather than end-customer sales. We focus specifically on Q4 2025 compared with Q4 2024, tracking changes in approval counts and market share for each major make. Top-ranked manufacturers are listed individually, while the remainder of the highly fragmented market is grouped into “Other makes”. Market share figures reference each manufacturer’s proportion of total small trailer approvals in Q4 2024 and Q4 2025.

Small Trailers
Q4 2025 saw 35,091 small trailer entries recorded on the Register of Approved Vehicles, up 5,149 entries from the 29,942 recorded in Q4 2024, representing a 17.2% year-on-year increase in total approvals. Alongside that strong volume growth, the top 10 named manufacturers now account for 51.3% of total approvals, up from 45.8% in Q4 2024, as ‘Other makes’ captured 48.7% of the market compared to 54.2% last year.
Top Five Manufacturers
The small trailer market’s growth in Q4 2025 was anchored by strong performances from the leading named brands. Other makes remained the largest component in aggregate, with entries increasing from 16,219 in Q4 2024 to 17,105 in Q4 2025. However, its market share fell from 54.2% to 48.7%, signalling that a greater proportion of approvals is now being captured by defined manufacturers rather than the fragmented, assorted manufacturers.
Among individual manufacturers, Stonegate Industries led the charge. Approvals jumped from 2,399 entries in Q4 2024 to 3,562 in Q4 2025, lifting its share from 8.0% to 10.2%. We interpret this as Stonegate converting strong demand into a much deeper presence on the RAV, widening its lead over the next tier of competitors.
Victorian Trailers also delivered robust growth, with entries rising from 2,095 to 2,579 and share ticking up from 7.0% to 7.3%. While the share gain was modest, Victorian Trailers maintained a solid second position among named manufacturers and extended its approvals base meaningfully year on year.
Century Trailers was another clear winner in Q4 2025. Approvals increased from 871 in Q4 2024 to 1,352 in Q4 2025, pushing share from 2.9% to 3.9%. That uplift confirms Century Trailers as a growing mid-tier brand that is steadily moving up the rankings.
Telwater Trailers continued to grow in absolute terms, with RAV entries rising from 1,161 to 1,194 between Q4 2024 and Q4 2025. However, given the faster expansion of the total market, its share eased from 3.9% to 3.4%. We see Telwater as a stable contributor to overall volumes, even as its relative position edged slightly lower in the face of more aggressive growth from Stonegate Industries and Century Trailers.
Closing out the top five, Dunbier reduced its presence on the Register, with approvals falling from 1,226 in Q4 2024 to 958 in Q4 2025 and share slipping from 4.1% to 2.7%.
The Rest of the Top 10
Beneath the leading tier, the rest of the top 10 featured a mix of retrenchment and rapid ascent. Superior Trailer Parts and King Kong Trailers also lost ground, with Superior Trailer Parts moving from 649 to 624 approvals and share easing from 2.2% to 1.8%, while King Kong Trailers declined from 733 to 610 approvals and from 2.4% to 1.7% share.
At the same time, a new wave of challengers emerged. The Bigman Trailers shifted from a negligible 4 approvals in Q4 2024 to 846 in Q4 2025, capturing 2.4% of the market and leaping into the top 10. MW Manufacturing moved from no recorded approvals to 567 entries and a 1.6% share, underscoring the segment’s openness to new or scaling manufacturers. These trajectories indicate that while some previously established mid-tier brands pulled back, others are stepping in to fill that space.
Market Fragmentation and the Role of 'Other Makes'
Despite its high level of fragmentation, the small trailer market in Q4 2025 showed clear signs of concentration towards named manufacturers. Other makes still accounted for nearly half of all approvals at 48.7% in Q4 2025, but this was a notable drop from 54.2% a year earlier. In absolute terms the group added approvals, increasing from 16,219 to 17,105 entries, yet the rest of the market grew faster as brands like Stonegate Industries, Victorian Trailers, Century Trailers, The Bigman Trailers and MW Manufacturing scaled their activity.
The multi-year RAV approvals timeline for small trailers underlines this structural change: many smaller brands continue to register modest volumes, but the bulk of incremental growth in Q4 2025 flowed to a relatively short list of leading and fast-rising manufacturers. We see this as the early phase of a gradual consolidation process in which the long tail remains significant but yields share to a more defined set of high-volume makes.
Trust Retain Media for Industry-Leading Insights
Overall, Q4 2025 small trailer RAV data points to a market that is both expanding and becoming more clearly organised around leading brands. Stonegate Industries, Victorian Trailers and Century Trailers built on their positions with strong year-on-year gains, while new entrants such as The Bigman Trailers and MW Manufacturing quickly established themselves inside the top 10. At the same time, ‘Other makes’ and several mid-tier brands surrendered share, even as total approvals climbed.
