I was unable to find any specifics in regards to the axle type or weight rating of your 2007 R-Vision D-300 but I do know it is a relatively lightweight tandem axle trailer, so the most likely option that will work is the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00.

This kit will fit a 2-3/8" round axle, which is typically found on 3,500 lb axles, so you do need to measure the diameter of your trailer's axle. The kit will then move your trailer's leaf springs to the top of your axle and lift your trailer approximately the same amount as your axle's diameter plus the height of the leaf spring pack (please keep in mind this conversion kit is for use with double-eye springs only).

I have added a link to a video review for you to check out as well of the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00.

Merely going with longer shackle links won't provide enough room for the suspension to articulate, you'll want to flip the springs back right side up. The way things are, you have zero articulation in the suspension which isn't safe.…

The U-bolt you're looking for is the #DX62FR, which is the replacement for the U-bolts in the Dexter Over-Under conversion kit. These U-bolts are 1/2" thick and 5-1/8" long. You could also just use the 2-3/8" Round Trailer U-Bolts…

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and…

The spring hanger placement is going to be determined by your axle spacing. For example, if your axles are spaced 33 inches apart, as shown in the attached diagram, a 7K axle slipper spring, like #e74SR, requires a distance of 28-1/2 inches between…
