Well, my idea for how the lift system works was WAY off. Wonder how they synchronize 4 separate lifts?

Like you, Brookside, I think the interior plan is pathetic. There's really no place to "hang out", unless it's on the bed. Even in our little 17 ft trailer, we can sit two adults and two grandkids on the couch.

It's not a trailer I'd want.

There are a number of ways to synchronize cylinders. Often a flow control valve is used that meters the same amount of fluid to all cylinders. Another way is to have a large cylinder attached mechanically to a few smaller cylinders. The ram from the large cylinder pushes the small cylinder rams in unison. The small cylinders act like piston pumps and send fluid to the actuating cylinders. Yet another way is to "daisy chain" cylinders. The first or master cylinder is connected to the pump. This cylinder has fluid on both sides of the piston. The backside of this cylinder is connected to the next cylinder, and so on. As the master extends it forces fluid out the the back and into the next cylinder, and so on.

None of the above are 100% accurate in their synchronization. leaks and wear can get things out of whack. But this can happen with our cable system. There are more sophisticated methods involving electronics but they tend to be expensive. Having said that, the price of electronics and digital circuits has come way down. Maybe TrailManor has found a way to do it inexpensively.

Rather than hydraulics I would prefer electrical actuation. There are a number of linear actuators available today that may do the job well. Many of these have the option to be interconnected for synchronization.

Papa and Brookside, thank you for the links.

Jack, there is nothing wrong with being "way off" here. After all, you and the rest of us are just brainstorming on this topic, and there is nothing wrong with that.

Ok, here goes my brainstorming idea. I did an assignment of ownership search for TrailManor's name. The only technology I found in their name was one U.S. patent, a patent that described their torsion system for manually opening and closing the roof wings of their current camper which they have been manufacturing for a good while. Then, I read again the newsletter Brookside provided in the link. TrailManor uses words like "the patented R-Drive hydraulic system." I also noted the artist rendering of the RISE camper which showed primarily the back side of the camper, not the front with the door at all. This was not a professional photo shoot at all, looks like something out of a drafting file. If TrailManor was really interested in going all out to manufacture this camper, they would have this camper sitting by a lake with people enjoying themselves with a front profile of the camper. Most companies who develop and subsequently issue a patent love to assert their bragging rights. Nowhere in this newsletter does TrailManor state "TrailManor's U.S. Patent . . ." It finally hit me; TrailManor does not own this patent; another company owns it. They probably have an exclusive license (or at present negotiating one) from the development company to practice the technology of the patent. Also, they could be attempting to buy this asset from the owner development company. (Papa and Brookside, I'm no good with links; you guys may have to link this for me.). Google without quotes "GTA Innovation LLC synchronized hydraulic systems." This article appeared in 2013 with a patent pending status stating that production would start in 2014. Don't forget to scroll down near the bottom and push the button for the YouTube video.

Good thing it has a remote, if it's as slow as it shows in the video, you would get soaked if it was raining. I believe I will stay with the Hi-Lo system. I don't really care for the looks of the new Trailmanor Rise. Even if I was interested in one I wouldn't buy one in the first year. All you need to do is go to is go to their site and read owner horror stories when they came out with the Elkmont hard sided camper

Link for Dee's info: Synchronized Hydraulic Systems - Whats New

I figured it out yesterday that you type your info and then copy/paste for link, to paste you use that blue thing at the top of the page where you are typing with the chain-link. I learned this on another website after several tries and with the moderator's help. I am technologically challenged.

Rich R: Thanks. When we first got a computer years ago, I had to have my 4-year old at the time help me. I'd say "Help Mommie make it stop!" or "Make it go.!"

I am guessing that Trailmanor is probably running behind so that is why they went ahead and used the photos that they had. It is almost the 4th of July and I am sure they had hoped to get the product out earlier in the spring or should have been thinking along those lines. They have been having "teasers" for awhile about it and people were getting anxious so why not throw them a bone?

It is always nice to see new ideas but I have seen a lot of ideas bite the dust. Jayco is getting ready to premiere yet another new unit after a failed attempt at a Euro-style camper they are at it again. When you can get a basic unit and for those that don't know quality from not, they see a $10,000 camper with $99.00 a month payments and then see a $30,000 camper........ Yet another reason that I love the classics!

The GTA system works like the second alternative that I described in my previous post: an actuator pushing 4 small actuators, each of them pumping fluid to the lift actuators.
