I have even seem THs with large sections of the frame webbing cut out to save weight. A frame such as that needs to be babied.Huntindog wrote:bobndot wrote:I am fairly certain that this is a hydraulic system..

From experience with electric rv jacks in general, motors can burn out and the tubes can bind, make sure you know how to repair them.
There location is susceptible to road dirt. When dealing with digital electronics it pays to use quality command modules and quality motors because you have 4 of them.
And it could be bad news no matter 4 or 6 jack if the trailer was not designed to accommodate it. Its not as easy as just taking off stabilizer jacks and adding leveling jacks. If they tell you not to "jack up/level" a trailer with the stabilizer jacks adding automatically operated jacks that raise the entire rig off the ground may not be the best idea?
One would think a company like Lippert who makes frames and the jacks, has the engineering who could tell you what would work and add additional reinforcement if required. Then again seeing that they produce standard tank support pieces that have been known to deflect and allow tanks to drop right out of a trailer, I'm not so sure LOL.
