If you change your existing jacks (hydraulic) to electric, you will still have the four wobbly (my opinion) legs, and the added cost of the Stable Lift is not that much greater. There are definate advantages to the Stable Lift and a couple of disadvantages. Areguments can be made for both systems depending on the type of camping you do. I suggest you do a search on this Forum for the Stable Lift to determine if it would work for you.
If your camping style is to offload your TC at your campsite, I think the hydraulic jacks are a big hassle, the electric jacks are a great improvement, and the Stable Lift is fantistic. If you go serious offroad, the lift may not work as well for you. I'm not talking about forest roads, I'm talking super rough deep creeks and trails stuff.
I have had hydraulic jacks on several TCs over the years. I have rebuilt several. They are pretty simple, and the last kit I bought cost about $50. Seldom is a kit needed, usually about 2 to 6 "O" rings from the local hardware store. Repairing electric jacks can get spendy. I've never needed to make repairs on my lift, but have priced the motor and gear assembly at less than $150.
The four jack systems are very wobbly. The stronger and gusty winds really compound the problem. Not an issue with the Stable Lift.
I have discovered a couple of things that are more comfotrable loading and unloading a TC with four jacks, especially hydraulics.
The most important is to leave the TC on the truck when camping, especially with hydraulic jacks. When loading or unloading try to avoid windy conditions.
At home, after raising the TC off the truck, block the TC at that height. There are several methods you can use to acomplish this. Leave the hydraulic jacks in the down position after you have unloaded.
With hydraulic jacks, when the TC is on the truck, use the safty bracket or chain to hold the jacks up. Then loosen the knob for the pump, and push the jack lever in. If you do not, the pressure in the jack will push the pump out and promote rusting of the pump shaft.
When you want to lift the TC with hyrdaulic jacks, disingage the safty brackets or chains to hold the jacks up, open the jack knobs about half way out. Push the bottom of the jacks to the ground. After doing this to all four jacks, tighten the knob of a jack and pump till you slightly raise that corner of the TC. Do this with all four jacks. This will bleed the air and prime the pumps.
I will pump one jack untill the opposite side is between 2 and 4 inches off the ground. I then go to the raised jack, loosen the knob, push the foot of the jack down, tighten the knob and give a couple of pumps to put pressure/load on that jack.
I will go to the other end of the TC and repeat the process. The objective is to raise the TC with the least amount of pumps pushing air. This is why I push the jack foot down with the valve/knob open.
I am sure you did not ask for a book, but I thought you might be interested in comparing how you and I might differ using our hydraulic jacks.
