what size trailer do i need for 4 atvs

I’ve been hauling a mix of ATVs and dirt bikes for five years on a 8x16 dual‑axle trailer. The extra length gives you room for the larger 700cc units without cramming, and the dual axles keep the weight distribution smooth. It’s a bit wider than a ramp‑style, so you need a wider lane, but it’s still legal on most state roads. I’d suggest checking your garage clearance; you might need to tilt the ramp a bit to get it in. Overall, it’s a solid, versatile choice if you don’t mind the extra purchase price.

For four ATVs, a single 8x12 ramp trailer can work, but you’ll be stacking two on each side, which isn’t ideal for balance. I tried it once and the rear tires wore unevenly because the load shifted during turns. If you go that route, make sure you use tie‑downs on all four vehicles and keep the weight centered. Also, consider a trailer with a higher deck height so you don’t have to lift the ATVs too far – it saves your back and speeds up loading.

We went with a custom 10x20 straight‑deck trailer last year because we wanted room for extra gear and a spare tire. The longer deck lets you place the two big ATVs side‑by‑side with the smaller bikes in front, which makes loading and unloading a breeze. The trade‑off is the higher purchase cost and the need for a larger hitch ball (2‑inch). If budget is tight, you could look at a used 8x16 and add a spare tire mount yourself – that’s what we did to keep costs down.

Safety first: whatever size you pick, make sure the trailer’s GVWR exceeds the combined weight of the four ATVs plus gear by at least 15‑20%. I once overloaded a 7‑ton trailer with three 700cc rigs and a bike, and the brakes started fading on the descent down a mountain pass. Also, invest in good LED light bars and reflective tape – visibility is key, especially when you’re hauling a wide load on night rides. And don’t forget to check your state’s length restrictions for trailers on public roads.

If you’re limited on garage space, consider a folding ramp trailer. They’re narrower when stored (around 6‑7 feet wide) but expand to an 8x12 footprint when set up. I’ve used one to haul four ATVs by loading two on the ramp and two on a small platform attached to the side. The downside is the platform can be a bit wobbly if not secured properly, so you need to double‑check the tie‑downs. It’s a good compromise if you can’t fit a larger trailer in your shop.
