I recommend going with Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers # AL88203 for your rear axle. This kit is confirmed to fit your 1984 P30. These air springs have built-in jounce springs so that you get the adjustability of air bags but also the comfort of jounce springs. Another nice way to look at it is that you will have a fail-safe backup plan if the air bags lose pressure in some unfortunate event. For a compressor I recommend Air Lift WirelessAIR Compressor System for Air Helper Springs # AL74000EZ. This has a wireless remote with a digital screen that allows you to monitor each spring's air pressure gauges. This also notifies you if a leak is detected.

If you are also looking for front air suspension as well, go with Air Lift 1000 Air Helper Springs for Coil Springs - Front
Item # AL81560. This is confirmed to fit your 1984 P30 and will need a second compressor for the front if you want to monitor and adjust the air pressure. I have attached demonstration videos for these kits.

I attached an install diagram for the Air Lift kit part #AL88203 that fits your 1989 P30 step van and in it you can see it does not attach to the leaf spring and instead to the axle and the jounce bumper mount.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
