Since you have 8K 3" axles you'll just need the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks - Tandem 8K, 3" Trailer Axles # RM-2460-2580.
The 3-1/2" requirement you were getting with the # RM-2470-2580 was simply because of the shock kit. I do recommend replacing your U-Bolts as well though with ones like # APUBR-9 as these get stretched and worn out after being torqued down and could potentially cause an issue down the road. These U-Bolts fit a 3" axle with 1-3/4" or... view full answer...
For your Fan-Tastic Vents you'll need the Fan-Tastic Vent Ultra Breeze Trailer Roof Vent Cover # DMC38FR. These covers are specifically designed for Fan-Tastic vents and will use the same screws that your vent uses to mount to the roof of your 2022 VanLeigh Vilano 390 fifth wheel. view full answer...
It appears that the HydraStar Disc Brake Kit # HSE7K-T1 is the correct kit for your 2021 Vanleigh Vilano 320GK. To verify this you can find the axle serial numbers and send that information to me so I can verify all the components are correct. Otherwise you can disassemble one of your hubs to verify your spindle measurements.
This kit uses
Inner bearing # 25580 (inner diameter 1.750")
Outer bearing # 14125A (inner diameter 1.250)
Grease Seal # GS-2250DL (inner diameter 2.250")

The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 will work with the factory hangers on your 2021 Vanleigh Vilano 320GK. This system is far superior to the standard Lippert suspension you have as it includes shocks for cushioning and allows the suspension to act more independently which increases traction to reduce sway. I do feel this is the best system available for the suspension on your 5th wheel. view full answer...
Definitely a smart idea to replace your Atwood heater with a tankless unit, as they are much more energy-efficient and quicker to heat your water. We do have an option that will easily fit in place of your 16" x 15-1/2" x 20-7/8" Atwood GC10A-4E, which is a unit from Furrion, and it will require the correct size access door as well:
- Furrion RV Tankless Water Heater # FR93FR
- Access Door for Furrion RV Tankless Water Heater - 18" x 18" # FR73FR
Th Furrion measures 19-3/16" deep x 12-5/8"... view full answer...
As your 2022 Vanleigh Vilano 320GK has a GVWR of 16,000lbs and uses 8,000lb axles you will need to use the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks # RM-2460-2580. This will have the 8,000lb leaf springs while the kit # RM-2460-2570 you found only has 7,000LB springs for a lighter axle. Both kits include the shocks for 3" round axles as well so you will be able to mount them on your axles. view full answer...
