GP, my understanding is that they are 'Stabilisers' only not stands or support legs. They probably ciuld hold the 2500kg BUT for how long is another thing IMO. I only use them to stabilise and if need I would use proper stands rated to 3t, again IMO.
I am currently checking out 3t aluminium stands on evilbay. Much lighter to carry around.

Stresses are in reverse for chassis in that case.
Designed to be suspended from Suspension out to ends.
with most Torsional stresses from\to, the front.
Jacks just to "stabilise.
Spend a coupla X $30's and buy a coupla prs of Axle stands.
Set them just outside of chassis radius where wheels would be.
with the weight on them. Then drop the jacks to stabilise.
Wheels inside to keep UV off tyres
and sticky fingers removing them or van.
You could use timber, But I've always used stands.
with Trolley jacks.
Have fun.
Remember to fully charge battery and Break away battery (if not built in.)
Then disconnect Neg cables.
or 2-3a Charger on mains and leave on float.
If inside and dry air.
Give a good coat of truck wash and don't wash off.
it'll hold all the dust.
Then when you come back and wash it down with broom and hose.
All the storage crap comes off. Even the spoggie pup.
Depends how long it's going to be sitting, long term say 10 mths or more I'd put stands under the fish plates, don't use the legs to take weight , for a short term using those curved plastic chocks that the wheel sits in would be fine, they keep the tyre round .
Always jack as close to the spring as possible as the further from the spring you can change the alighnment as the axle may bend slightly...

Checking out the places I drove past a thousand times................
After 50 odd yrs.
I use Trolley jack for my vans.
Run between wheels either side. and lift straight up.
I use it to level van O'Night
(just remove handle to stop anybody tripping over it.)
Half a doz strokes. Either side up for wheel removal.
Bearings.Brakes, Whatever.
without ever getting on your knees to place little wobbly jacks.
With a coupla Screw jack axle stands
for longer term parking.
Plus. This way you jack off the chassis rails all the time.
Mainly just the two reinforced Suspension mount points.
NO underneath van at all.
1.8ton will cover 99% of vans and not too heavy
2 ton a lot heavier.
and only certain (better quality) 1.4 ton jacks will lift stated weight.
Worth finding.
As others have stated there not there to take much weight at all, when we first bought our van the floor used to creak,and I was not putting what I thought was too much tension on the legs,but using even less tension on them has fixed that problem...
A quick look at the stabs will show they are not for load bearing, since all the weight is taken up on a couple of 5mm at most bolts.....and the wind down scissor type will bend sideways if used as weight bearers.............................I try to get away every couple of months so don't worry about it.
