The jack is one of the hardest-working parts on an off-road trailer - it carries the nose weight every time you hitch, unhitch and level. A cheap jack bends or seizes the first time it eats dust and mud. The ARK XO range is what a lot of overland trailer builders in North America spec as standard, and it comes in three sizes. Here's how to choose.
The quick answer
- ARK XO350 - the lightweight of the range, ideal for teardrops, small utility trailers and compact off-road campers.
- ARK XO500 - the mid-size all-rounder for hybrids and mid-weight caravans that don't need maximum capacity.
- ARK XO750 - the toughest in the range, built for heavier off-road campers and full caravans.
What actually matters in an off-road jack
Load rating. Match the jack to your trailer's nose weight with margin to spare - an undersized jack is the one that fails. The XO750 carries the highest rating, the XO350 the lowest.
Sealing against dust and water. This is where cheap jacks die. The XO range is built to keep grit and water out of the mechanism, which is exactly what you want after a corrugated track or a river crossing.
Travel and ground clearance. A taller lift makes hitching on uneven ground far easier. Bigger jacks generally give more travel.
Weight. Every pound on the drawbar matters. If your trailer is light, the XO350 saves weight; if it's heavy, don't undersize to save a few pounds.
Which ARK jack for your camper?
Lighter campers and teardrops are well served by the XO350. Mid-size hybrids - think MDC XT-series or OPUS - typically suit the XO500. Heavier hard-wall caravans like the larger Black Series HQ models are XO750 territory. There's also a blacked-out XO500 Black Edition if you want the look to match a murdered-out build.
