Viper is a brand name and I can understand your desire to use one. That being said, you probably know that Directed ( DEI ) and Viper will not provide any installation support nor warranty on any of their products that are not installed by one of their dealers. ( Of course, most other manufacturers in this field have the same policy. )
Now for the fun part. Your truck needs a bypass module. For most newer vehicles, a bypass module is the easy way to go. They do a whole lot more than just bypass the transponder immobilizer system. The previously mentioned DBALL2 can do this but it needs to be flashed with 402.GM10 Ver 4.23 firmware. This can be easily done with a XKLoader3 or 4 and Dealer access to their restricted WEB site. I'm guessing that you are not a Dealer and don't buy $2,000 worth of DEI products every quarter. If the seller ( SonicElectronics ) can properly flash this bypass module for you, then you are all set, as it does not require any additional programming to be installed.
Next comes your budget. Getting a remote start and alarm system with a full function bypass module for under $200 is possible but would be a one way remote system with a max range of 1,500 feet. Your additional request for added security to prevent theft could be handled by a circuit to prevent Starter Motor engagenment while the Viper alarm is set. This would reqire a relay and the use of this vehicle wire : Starter yellow (for starter kill only) + starter @ underhood fuse box, green 58 pin plug, pin E2
A good alternative to the Viper is a Computar CS7900AS system. It will give you the R/S and Alarm functions with a longer range of 3,000 feet plus one on the remotes is 2-way for $140. The best bypass module for the Compustar is an iDatalink ADS AL-CA module. It would have to be flashed with the ADS GM7 firmware but there are sellers that will do this prior to shipment with a total price of $55. Still under $200, but a better system. The starter kill relay is a basic +12V SPDT relay with a harness. They go for about $5 if you don't have you available from your job.
A few notes...
Assuming your truck has an automatic transmission. Assuming power door locks. The install can vary on OnStar and OEM Alarm equipped vehicles. Pretty easy install, most everything is done at the BCM and OBD2.
Soldering is fun!
