Will the rear jacks (18" model) available from scamp work well for stabilizing purposes once I have leveled the trailer?

Roy, my frame is most definitely too low. I am trying to work though the design for a new axle as you did in your writeup and install that this coming spring.
I found these at Grizzly Tolls. I bought 4 of them & had a piece of channel iron welded on top of them so that they would fit onto the frame. When I get to the campsite, I park the camper, get the 4 jacks out, put them at the 4 corners & level it up. Couldn't beat the price.

Now stick that hooked piece into a cordless drill and presto, you have power jacks.

Libby, careful. You shouldn't use these on the four corners of the frame to level. Use them to stabilize the trailer only. You may tweak the frame out of shape, or cause some hairline cracks. Leveling is done side-to-side at the wheels, and front to back with the tongue jack. Once level, the Grizzly jacks look like they'd work well for stabilizing.... only.

Safe travels

I am new to North American FGRVs but not that new to light trailers with noodle like frames... Personally, I like scissor jacks. Easy to use, (with extension) they are easy to crank up and adjust and relatively sturdy. Grizzly may be low but after factoring in the shipping, it may be cheaper to stop by a car scrap yard where similar jacks are a dime a dozen.
Donna is right - AFAIK most eggs have rather flimsy frames so, lifting fully up on the corners can put a considerable stress on the frame. By the same token, you put extra stress on it when you use the tongue support jack and two at the back of the frame. If you lift it off the wheels, the middle will sag = stress. If you leave most of the weight on the wheels and use tongue / rear jacks just to stabilize, two people are the front of the trailer, it starts to sag (less but noticeably) between the tongue and the wheels. The rear jacks may even come (almost) loose and the trailer may start to wiggle... well, depending at what the two are doing at the front Not that good. It's a fine balancing act. IMHO, the best is to distribute the weight between the middle (by the axle) and corners of the frame. Easily done with 6 scissor jacks but requires some crawling on your knees. Worth it for a longer stay. Start with levelling front / back with the tongue jack wheel. Next, put two jacks under the axle (or frame right by the axle) and it doesn't matter much if one of the wheels goes fully up. Than, level front to back again with the tongue. Next, snug up 2 jacks under the from corners of the frame. next, release some pressure from the tongue wheel / jack. Lastly, snug up two jacks under the rear corners of the frame. Wipe the sweat and have some wine or beer or better yet Canadian whiskey. Your trailer is sturdy as a rock and any stresses are well distributed between 6 jacks and whatever is in the glass Oh, set the jacks so the middle is along the length of the trailer and front and back are along the with. Kind of like |=| Alternately, if you hate crawling on your knees as much as I do, put the ones under the axles on 45 deg to the axle < and same for the front / back. Kind of <>< The reason for this is; scissor jacks are sturdy along the axle bot bendy side to side. The above arrangement minimizes the swing of the trailer when on the jacks.
Hopefully, even with my much less than perfect English, you get the picture of what am I trying to say and that helps somebody.
YMMV

BTW. Forgot to ad at first; most car scissor jacks extend to less than 12" and have rather small bases. Just get a bunch of 1' square 3/4" plywood pieces to put / stack up under the jacks. Shellack them well and they will last forever and will support your egg even on a soft sand.

A morning correction -I guess, because of my flue, I wasn't thinking right. In the last post I wrote "put two jacks under the axle (or frame right by the axle)" NO, don't put theme there on the frame. I was thinking about a trailer with swing arm suspension like my Cadet was - there the middle set of jacks went on the ends of the arms, right by the wheels. The middle has to be supported by the trailers suspension so front and rear jacks wouldn't come loose. Oh and obviously, if where you put the trailer is level side to side to start with, there is no need to use the middle set of jacks at all.
