Thank you for allowing me to join.
Can anyone tell me where I can find replacement seals for the lift cylinder? My trailer raises just fine, it won't stay up. Goes back down at a steady pace. I've replaced the solenoid and the solenoid coil already.

I did a search and here is what I came up with. A post from Hellbender 6-30-2023. It gives the parts numbers and where he ordered from.

Woodrow - welcome to the forum. You MAY also have a small bit of debris in the lowering valve, keeping it slightly open, which would also cause the top to settle when up. There is a procedure for clearing this valve in the forum. I THINK it simply involves raising and lowering the top a couple times.

Welcome to the forum. Try this procedure before you go through the work of replacing seals, etc. Good luck.
