Being an RST owner I thought I would chime in. These trucks were offered in 2 packages...the first was a 4.8/5spd combo in a RCSB set up. The second was 5.3/ Auto setup in ether a RCSB or an ECSB set up. They had an interior package, lowering kit, 20' wheels, big brake kit, CAI, headers, exhaust and bunch of other stuff that will take too long to list. I am not aware of an LS2/ T56 model or a supercharged model. And I know everyone had their own opinion, but I have never had any major issues with my truck, it has been one of the best vehicles I have bought!

 

Thats the RST packages. Then the supercharged JoeGibbs package was a RCSB 4.8/ 5speed with a magnacharger or RCSB 5.3/auto with a magnacharger. I THINK. Then there is the Jon Moss RST, not sure what it had. But I've never heard of an LS2/T56 model.

 

To have had no major problems with your Regency, you should definately feel like you are blessed. These trucks aren't brak down prone but when the parts fail they are indeed an act of congress, to aquire. It took Regency 91 days to ship me a set of Foose 22 wheels fro a Regency Tahoe that had failed. So...the turn around time was extremely poor.

By the way...there were several more packages available with the Regency pickup.

 

I know that Regency offered other trucks and SUV's but I was not aware of them carrying the RST name.
