Is support needed when storing for an extended time?

[BigSwick]

Hello all. I am fairly new to truck campers, about a year now. I have been leaving the camper- Cirrus 820- sit on the jacks when not in use. Sometimes for a month or two. Is a platform or stand needed to take the weight off of the jacks when not in use? And if you use them, how did you construct them? TIA and Happy New Year!

I bought those screw jacks for my van conversion to prevent the movements. Had then originally on 1969 Airstream so this is well-experienced design. You'd be amazed with load capacity of them.

I used to use composite pallets with cross timbers to spread the load. Now I use inexpensive screw jacks (come in sets of four $40) and 4x4's to spread the load. They may not be required, but they definitely help share the load off of just the four corner jacks.

I left my big camper on jack only, when it was about 10 yo and after couple of days weight of water tank start separating the floor from the frame.
Camper had some water damages, who participated in floor separation but since that I was always supporting front of camper floor, what also cut down camper movements when we walk inside.
Simple 4x4 at 48" under front floor edge and 4x6 cut to size to keep the camper at optimal level did the trick.
Later on I was able to find aluminium 4x3 tubing, who was better material for the job, but my goal was to carry it with me as we drop camper on our travels quite often

I never stored my TC unsupported. Safest way is how the TC is supported when on your truck IMO.

Not needed, unless you are needing to stabilize it more for say using it while off the truck.
When we first got a TC I thought it was something that was needed, then realized that it's not. Last camper sat for probably 5 years on jacks only.

No, but highly recommended.

Until a big wind or other force pushes on the TC you will be fine.

I made mine with one sheet of treated plywood. I made the X. Cut in half short-ways, so two 4 foot squares.
Cut slits of the same width as the board is thick (so 3/4 inch wide slits for a 3/4 inch thick plywood).
Cut the slits only half way. The slits are from the center of one edge to the middle.
Put the two slighted boards together to make an X, or T (+).

Make another one of these.

Put under TC.

You can add boards across the top if you like the camper to sit on more than just two X's.
I put the X's on bricks to keep it off the wet concrete.

This takes weight off TC, but you can still have the legs holding up some weight to give TC a wider footprint.

Others have used a couple of saw horses. Yet others have used stacks of shipping pallets. Bricks. Anything works that you can render....
