Question Scissor Jacks?

Just bought an sv264 and found on our first trip that leveling was a bit more involved than the pop up I had years ago. We like to go the mountains along the Blue Ridge Parkway in Virginia and NC. The national park service has done a lousy job of creating level sites, even though they're paved. Some of the private campgrounds aren't much better. Some trailers had one side up as much as 6''. We have boards, but after hassling with the stabilizers and a small hydraulic jack, I thought scissor jacks might be in order.

We checked out some Ultra Scissor Jacks and they seem to be priced at about $55 for a pair at Camping World. Is this a good quality product? Also I noticed that some trailers had jacks only in the back, while others had 2 in the front as well. Which is the best way to go?

I managed to buy a couple of scissor jacks direct from Lippert for about $32.00 each, if I remember correctly. If you are thinking of picking the trailer up with them, it won't work. You must keep the wheels on the ground.

Easiest way to level is to have enough boards, lynx levelers, lego blocks, whatever, to put under the wheels to get the side/side level correct. Then unhook, and use the tongue jack for front/rear level, then and only then put down the scissor jacks. I can adjust my side-to-side level an inch or so with the scissor jacks on each corner, so that doesn't have to be perfect. Never lift the wheels off the ground as this will cause an unstable condition since the top of the scissor jack even bolted to the frame will not prevent a forward or backward shift, and subsequent collapse of your trailer.
My 2 cents, others will chime in I'm sure.

Same here, not made to lift, only stabilize, and to answer your questions on how many, you need one for each corner, including the front.

Thanks Windrider,

If you only use them for slight adjustments, why not just use the stabilizers? In addition to the boards for leveling, I plan to get a good set of wheel chocks.

I read it as using both, just don't try to lift the weight off the wheels, rather to stabilize the movement and if you lift a little that's ok

I use a 2x6 treated lumber that is 4 1/2 foot long under the wheels and i carry two of them with me. The yellow blocks are great because they are lite weight but I have found that if i but them on the ground under the jacks they have a tendency to walk into the dirt or sand so I place a board that is just a little larger then the yellow blocks under the blocks so that they are on something solid which helps. Now the other thing I have found is that the higher I go with the yellow blocks the more flex there is. It would be better if the yellow blocks were solid.

bmg, I have the sister ship to the SV264....the SV263. The frame is a lite-weight I beam. No way would I try to lift much weight at any point on the frame, except maybe near the axles. If you notice, the axle connection points have extra support there.

I level my camper as close a possible with blocks, and might "tweak" it a little with the stab jacks on the low side, put the jacks down on the opposite side, then call it a day.

I hope there's no prohibition against asking dumb questions, because I'm probably about to. I've tried to research some of this, but both the owners manual and my Woodall's RV Handbook don't even talk about the stabilizers/jacks.

I'm under the impression that the stabilizers are not referred to as jacks since you can't raise any weight w/o breaking them. In talking to Camping World it seemed that they wanted to remove the stabilizers and replace them with the scissor jacks. From what I'm sensing here is some of you have both and have the scissors installed closer to the axles. Am I understanding that correctly? If so it would seem that the sequence would be: 1. leveling with boards under the wheels, 2. chocking the wheels, 3. using the scissor jacks for minor leveling, and 4. putting down the stabilizers to secure the corners. Am I on the right page here? Any feedback would be greatly appreciated.

Most have found the "1 arm" stabilizer jacks don't do a good job, too much flexing, especially if they have to go past half way. My trailer came with scissor jacks on all four corners. I purchased two more to make a deck out of my "toy hauler" tailgate. The scissor jacks will pick my trailer up, but a toy hauler has a very strong frame, some campers don't. Is not advised to do this when not connected to the tow vehicle, as there is nothing to keep it from being pushed over. Always leave some pressure on the tires, but lower jacks enough to stop any suspension movement, or in other words, raise trailer slightly.
