Each set supports up to 8,000 pounds, carries by a molded T-handle, and nests flat for storage. Simple, tough, and built to work with the square blocks you already run.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eAnybody who's spent a weekend at a campsite knows the drill. You pull into the spot, drop the jacks, and the whole rig still leans because one corner sank into soft grass or gravel. The Camco FasTen 44539 Big Blocks are the fix for that. They're a two-pack of heavy-duty plastic bases with a molded T-handle, built to sit under your leveling jacks and square blocks so the weight spreads out instead of driving down into the dirt.\u003c\/p\u003e\n\u003cp\u003eHere's the short version. Each set handles up to 8,000 pounds, which covers the jack and stabilizer loads on most travel trailers, fifth wheels, and motorhomes. You place a block under the jack foot or under a stack of square leveling blocks, and the wide base does the work. No more chasing a level bubble because one corner keeps settling overnight.\u003c\/p\u003e\n\u003cp\u003eThe T-handle is the part you'll appreciate at 9 PM when you're setting up in the rain. It's molded right into the block, so you grab one in each hand, carry them to the jacks, and set them down without bending over to wrestle a flat slab. When you're packing up, the two blocks nest together and stack flat. That means they slide into a storage bay and stay put instead of sliding around and banging into your other gear.\u003c\/p\u003e\n\u003cp\u003eThese are made to work with the leveling setup you probably already own. They're compatible with square RV leveling blocks and RV jacks, so if you run the interlocking square blocks under your tires or stabilizers, the FasTen Big Blocks give you a wider, more stable foundation underneath. Think of them as the base layer. Soft ground, loose gravel, a grassy pull-through that turns to mud after a storm, this is where they earn their keep.\u003c\/p\u003e\n\u003cp\u003eWhy plastic instead of wood? Because a scrap 2x6 rots, splinters, and warps after a season of getting rained on and run over. This molded plastic won't soak up water, won't rust, and won't crack the way a dried-out board does. Hose it off, toss it in the bay, done. It's the kind of gear you buy once and forget about, which is exactly what you want out of a leveling accessory.\u003c\/p\u003e\n\u003cp\u003eA quick note on what these are and aren't. The 44539 set is the big base block with the T-handle, sold two to a pack. They're designed to support jacks and square blocks, not to replace a full drive-on ramp for running your tires up. If you need to raise a low tire, you'd stack square leveling blocks on top of these. Used the way they're meant to be used, as a stabilizing foundation under jacks and stacks, they're hard to beat.\u003c\/p\u003e\n\u003cp\u003eSetup is about as simple as it gets. Pull into your spot, figure out which corners need support, and slide a Big Block under each jack foot or block stack before you lower everything down. Crank the jacks, check your level, and you're set. When it's time to leave, raise the jacks, grab the blocks by the T-handle, give them a rinse if they're muddy, and nest them for the trip home. There's nothing to assemble, nothing to wear out, and nothing to plug in.\u003c\/p\u003e\n\u003cp\u003eAnd it's not just RVs. If you store a boat on a trailer over the winter, or you're working on a trailer that needs a stable footing on a sloped driveway, the same 8,000-pound base does the job under trailer jacks and stands. Wide foot, big capacity, easy to move around by the handle. For anyone who deals with jacks on uneven ground, these are a genuinely useful thing to have in the truck.\u003c\/p\u003e\n\u003cp\u003eIf you camp on anything other than a perfectly poured concrete pad, and most of us don't, a pair of these belongs in your storage bay. They're a small, inexpensive piece of gear that saves you from a rig that rocks every time somebody walks across the floor. Level, solid, and quiet. That's the whole point.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e8,000 lb load capacity per set supports the jack and stabilizer weight of most travel trailers, fifth wheels, and motorhomes without flexing\u003c\/li\u003e\n  \u003cli\u003eMolded T-handle lets you carry and place each block one-handed, even with muddy gloves on at the end of a long drive\u003c\/li\u003e\n  \u003cli\u003eNesting design stacks the two blocks flat so they tuck into a storage bay instead of rattling around loose\u003c\/li\u003e\n  \u003cli\u003eCompatible with square RV leveling blocks and RV jacks, so they drop right into the leveling setup you already run\u003c\/li\u003e\n  \u003cli\u003eWide footprint spreads jack and stabilizer load across soft ground, gravel, and grass to stop the rig from sinking\u003c\/li\u003e\n  \u003cli\u003eMolded plastic construction shrugs off water, mud, and sun without rotting, rusting, or splintering like a wood board\u003c\/li\u003e\n  \u003cli\u003eSet of 2 puts a stable base under two jacks or two block stacks at once\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Camco reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat's the weight capacity of the Camco FasTen 44539 Big Blocks?\u003c\/summary\u003e\n    \u003cp\u003eEach set is rated to support up to 8,000 pounds, which covers the jack and stabilizer loads on most travel trailers, fifth wheels, and motorhomes.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow many blocks come in the pack?\u003c\/summary\u003e\n    \u003cp\u003eYou get a set of 2.
