The front left drivers door should have another VIN plate with the Starcraft number. The front suspension is a Neway air-ride unit with quad shocks. The shocks should be Neway part# 90044794 which will crossover to Monroe Gas Magnum 60 part# 66633, or Gabriel FleetLine part# 83127. The rear suspension is a Reyco 101A-AR air-ride with Monroe Gas Magnum 60 part# 6710 which crossover to Monroe Gas Magnum 65 part# 65401. If your suspension rides rough or your motorhome "wanders" while you drive I would also check the air-ride height control valves located behind each front wheel. The inner core valve for the dump/exhaust port will sometimes partially fail causing an overinflated airbag and rough ride that the shocks cannot compensate for. The valves should be Haldex type CR controlled response height control valves part# 90054007.
From what I have found Starcraft made 8 of the 370UR diesel pusher motorhomes and numerous gas models. The first 2 were used by Starcraft for RV shows and dealer demos I was told. If you look at your Starcraft VIN (the motorhome has two VIN's, one for the Spartan chassis and one assigned by Starcraft) that starts with 1SAUR - the very last number should tell you which unit you have off of the assembly line. I currently have unit number 4. Parts are still readily available for the chassis through Spartan and I have found them to be competitive with outside vendors for direct replacement. For the motorhome - parts can be found from the original individual parts manufacturer for most items, to date the only two parts I cannot find are the original through wall stove vent and side body molding. Unfortunately Starcraft sold the motorhome division to Jayco in the 1990's so limited to no help will be provided if you call either with questions. I hope this helps.
Congratulations on the Starcraft motorhome…I do have all of the original paperwork to include the factory brochure that I have scanned into a pdf. file that I can send. The owners manual for this motorhome is actually on VHS tapes if you would like I can convert over to DVD and send you a copy. I have owned my Starcraft for several years, purchasing from the original owner who had only put 6,800 miles on the unit. I have virtually been through my entire motorhome fixing, modifying, or updating where the factory fell short. If you have any glitches or wiring problems let me know - I have solved several on mine.
Send me an email with your address and I will send out the DVD.
