BETTER THEN A LIFT KIT.I own a 2018 19RBS . It has the potential to be a super trailer. Like all trailers you need to improve them as you own them. Rather than replace the brakes. Use this time to do improvements.change the axle to a straight 5400 to 6000 lbs axle (same price as brakes) It will allow you to use higher rated tires. It will allow you to dump your waste tanks easier. The axle on the trailer will only allow you to use tires that are max out to the trailer weight..this will cause tire blow out that will be very expensive to repair if possible. The new axle will handle the weight of the trailer better.. you will need a new tire size 15” but one tire 14ply tire can handle more then 150% of the entire weight of the trailer. That means no blow out.. 14” tire are at there max weight capacity..I order a complete axle with brake for very little money. I added 6000 pound springs..I bent a spring also before I done this.. adding these improvements was the best thing I did to my vista cruiser.. love it now bulletproof. This applies to raising your trailer and improving over things at the same time.. straight axle will lift your trailer.. you have a 4” step down axle.. if you own a visa cruiser.. all rv manufacturers used axle at there max weight capacity..causing tire blow out.bent axles
