I have a 40’ Monty two axels and need to know how am can lift it up so one wheel is off the ground. The manual says use a jack on the frame by the spring mount that would seem hard on the trailer. I have one of those half moon ramps that you drive on and it raises one tire off the ground. Does that sound safe for the trailer?
Mine doesn't have all that fancy stuff LOL
I just use a bottle jack under the axle where it bolts to the spring. Make sure you ether hook it to the truck or chock the wheels real good. When I cha;lk my wheels I put one behind the rear of the tire. Then I put the truck in reverse and put some pressure on the rear chalk. Then I put the front one in and shift to natural. Let the truck roll forward and that locks the wheels pretty good. I can tell because you cant just pull them out.
To also answer the OP's question, yes, the half-moon thing is a good way to lift one wheel. Before I had Level Up (which I haven't used yet to lift the rig since I haven't had a flat...yet) I used a bottle jack under the ubolts. Should also be nothing wrong with lifting at the frame as stated in the manual...you just have to lift higher to get the wheel off the ground.
There are several ways to skin this cat...mostly common sense with safety in mind.
