to the forum from W TX and congrats on the new rig. Sounds like you've been doing your homework. The Ram 1500/5.7/3.92 is a capable rig - I owned one.
You've probably crunched the numbers but keep in mind;
Your truck is "rated" to tow 10,150. The trailer weighs 6768 and has a payload of 4222,or max trailer of 10,990 - well over your tow limit so watch what you load. I don't know what the two bikes weigh (maybe 800 each?) but that will give you a significant load right away.
The payload for your truck will be about 1500lbs. The dry hitch weight of the trailer is 830 and will go up - probably significantly. Whatever it comes to it must come off the payload. You will have less than 500lbs of payload left for the truck if that much....the weakness of the 1/2 ton.
Load wisely (take only what you have to have), weigh it all at the scales, be safe, and most of all....have fun!
I pulled a 9000lb trailer with the same truck and that was all she (or I) wanted - bought a new 3/4 ton.
