Quick answer: Every van and camper setup needs two things: a pair of solid rubber wheel chocks to hold it, and interlocking levelling blocks to fix the slope — that combination handles almost any site. Drive-on curved ramps are the quicker fix for single axles, combo ramp-and-chock sets keep the kit tidy, and clamp-style chocks add stability on tandem axles. The bargain-bin plastic wedges are the ones to skip.
Nobody advertises it, but almost every campsite slopes somewhere. Park a caravan or camper trailer on that slope and the doors swing themselves shut, the bed rolls you into your partner, and if you run a three-way absorption fridge it can stop cooling altogether — those fridges rely on gravity to circulate their coolant and sulk when parked well off level. The first ten minutes with chocks and ramps decide how the next three days feel.
There is a safety layer under the comfort layer, too. A handbrake is a parking aid, not an anchor: it acts on some wheels only, through a cable that stretches, and a couple of tonnes of van on damp grass will test it. Chocks are the cheap, dumb, reliable backup that never has an off day. Here is the gear that does the job properly, and the flimsy stuff that only looks like it does.
Quick Picks
- Best overall: a pair of solid rubber wedge chocks
- Best for levelling: interlocking stacker blocks
- Best one-move fix: drive-on curved levelling ramps
- Best tidy setup: a ramp-and-chock combo set
- Best for tandem axles: clamp-style dual-wheel chocks
How to Choose Chocks and Ramps
Start with weight, because that is where cheap gear quietly fails. Every chock and ramp worth owning has a load rating moulded into it — check that it comfortably covers the weight sitting on each wheel of your van, then treat that number as a minimum. Heavy vans on hot days will find the weak point in brittle bargain plastic, and a chock that splits under load fails at exactly the wrong moment.
Then think about how much lift you actually need. Interlocking blocks typically stack to raise a wheel around 10 cm, which corrects the great majority of sloping sites; curved drive-on ramps give a similar range in one movement instead of a stack. Rubber grips wet grass and smooth concrete far better than hard plastic, at the cost of weight and a bit of boot-space. Finally, count your axles: tandem-axle vans are awkward to ramp and are better served by clamp-style chocks that lock between the paired wheels. Whatever you choose, it should be the second thing out of the boot — chocks go in before the coupling comes off, every single time.

Solid Rubber Wedge Chocks
The unglamorous essential. A pair of solid rubber wedges grips wet grass, gravel and polished concrete alike, will not crack in heat or cold, and their dead weight is a feature — they stay planted while you nudge the van onto them. Look for a moulded load rating, a rope handle or eyelet so you are not fishing under the van by torchlight, and enough height to sit deep into the tyre’s curve. This is the item where buying heavy and ugly beats buying light and clever. Check current rubber wheel chocks stock on Amazon.
Interlocking Levelling Blocks
Think oversized toy bricks rated for tonnes. Interlocking blocks — the style Camco and Milenco are known for — stack to whatever height a site demands, spread the load over a wide footprint so wheels do not sink into soft ground, and double as pads under a jockey wheel or corner steadies. They are the most versatile levelling buy because a slope is never the same twice. The trade-off is faff: you build a small staircase, drive up in stages, and a spotter helps. Browse the current caravan levelling blocks listings on Amazon.
Drive-On Curved Ramps
Curved ramps — Fiamma’s Level Up is the shape everyone copies — trade the block stack for one smooth roll: drive up until the bubble level reads happy, chock, done. Because the curve supports the tyre continuously you can stop at any height in the range rather than the fixed steps a stack gives you. They suit single-axle vans and motorhomes best. Two watch-outs: they slide on slick ground unless the surface grips or the ramp has teeth, and steep curves can foul low bodywork — check clearance before you commit. Find the right caravan levelling ramps on Amazon.
Ramp-and-Chock Combo Sets
The tidy answer. Combo sets pair a curved ramp with a matched chock that nests against the tyre once you are at height, so the wheel cannot roll back down the ramp it just climbed — the failure mode people forget when they level first and reach for the chocks afterwards. Everything stacks into one block for the boot, and nothing is left to improvise. If you are starting from zero, a combo set plus one pair of rubber wedges is the whole kit sorted in two purchases. See how the wheel chock ramp sets options stack up on Amazon.
Clamp-Style Tandem Chocks
Tandem-axle vans get a purpose-built option: a scissor or clamp chock that winds out to lock between the two paired wheels, pressing against both tyres at once. Because it braces the wheels against each other it does two jobs — it stops rolling and it kills a surprising amount of the rocking you feel inside the van when someone moves around. Wind it firm, not heroic, and remember it works on the pair: single-axle vans should look elsewhere on this list. Check the latest tandem wheel chocks range on Amazon.
Comparison
| Option | What it does | Best for | Weak spot |
|---|---|---|---|
| Rubber wedge chocks | Holds the van still | Every setup, every site | Heavy in the boot |
| Interlocking blocks | Stacked lift, ~10 cm | Soft ground, variable slopes | Slower staged setup |
| Drive-on curved ramps | Any-height lift in one roll | Single axles, quick stops | Can slide on slick ground |
| Ramp-and-chock combos | Lift plus lock in one kit | First-time buyers | Bulkier than either alone |
| Clamp tandem chocks | Braces paired wheels | Tandem-axle vans | Useless on single axles |
Frequently Asked Questions
Do I chock before or after unhitching?
Before, always. The tow vehicle is what is holding the van on any slope; chock both sides of a wheel first, then release the coupling. Reverse the order when leaving — hitch up fully before the chocks come out.
How level does a caravan fridge actually need to be?
Three-way absorption fridges want to be close to level — visibly off-level for hours hurts their cooling and can shorten their life. Compressor 12V fridges do not care. If you are unsure which you have, level the van properly and both types stay happy.
Are rubber chocks really worth it over plastic?
For heavy vans, yes: rubber grips slick surfaces and shrugs off heat, cold and UV that turn cheap plastic brittle. Good engineering-grade plastic chocks are fine under lighter campers — the moulded load rating, not the material alone, is the deciding line.
Can I just carry a few blocks of wood instead?
Timber offcuts work as load-spreading pads under jacks and steadies, and plenty of people travel with some. As chocks or ramps they are a gamble — no grip profile, no rating, and hardwood splits without warning. Spend the small money on the real thing for the job of holding the van.
The Bottom Line
Buy the boring pair of solid rubber chocks first — that is the pick, because everything else on this list assumes the van is already held still. Add interlocking blocks if your sites vary or the ground runs soft, choose curved ramps if you value speed on a single axle, and fit clamp chocks if you tow a tandem. None of it is exciting gear, and all of it is cheaper than one panel repair from a van that walked off its handbrake.
