I have been lucky out on the road and haven't yet had that flat but know it will come one day. I carry a 12T bottle jack. Everything I can read talks about lifting either on the frame right behind the springs. I have seen such in pictures within some of the RV manuals but they are always using a big commerical type jack, ultimately lifting both tires off the ground. I have seen the plastic deals where you simply pull your good tire up on it to change the other flat tire. My trailer has the MorRyde stablizer system on the springs. Anyone have any experience using the drive on lift for changing a flat out on the road? Sure looks easier than having to mess with a bottle jack and blocking?
I have not used any drive-on type lifting device other than to support both axles when leveling the fiver. I don't think I want to use something like that when I've already got a couple of good 8T bottle jacks. I've changed two tires on my fiver and used the bottle jacks at the axle rather than at the frame. I also have Moryde suspension but with tandem duals supporting a 20K# trailer (16,500# on the axles). For safety, I also support the fiver with jack stands. I lift the tire barely high enough off the ground to get the inflated tire back on. Unfortunately, both flats were inside tires.
I guess I'm missing something, because I don't understand why I should jack the frame rather than the axle on my fiver. I put less stress on the axles, springs and Moryde and it should be as safe if not safer.

I have always used a bottle jack and place it on the axle u bolt or the plate on the bottom of the u bolt depending on the instillation of the u bolt, up or down.

I always used the shackle plate under the spring also. Could never understand why this is not recommended. Not putting the jack under the round axle tube I can understand. But why not the shackle plate?
I use the drive on ramp. Works great on hard surface. Will sink in on soft ground. Carry a piece of plywood, or a 2X6 to go under it on soft ground. Much better than jacking. Quicker, safer for any wheel maint. And for adjusting brakes, it is out of the way.
If using a jack, be sure to hitch the trailer to the truck, rather than expecting the front elevators to hold the weight.

Do NOT jack on the axle of a Mor/ryde system, you will damage it. Consult your manual or better yet contact Mor/ryde at (574) 293-1581. I could tell you were to jack, but I'd rather you get the correct info direct.
I carry around a 12" block of wood to put the bottle jack on. Also leave trailer on the truck to eliminate any twisting on landing legs. As per earlier post, position jack just aft of rear spring hangers.

My axles are made by Lippert Components and their manual says, “Warning: Lift unit by the frame and never the axle or suspension.” My 5er’s manual says the same thing.
