I have a 2005 silverado with the 5.3L engine and 4.10 rear end, was just wondering if anyone has much experience towing with a similar rig and what the size limit would be when considering an RV. I have an AEM intake and flowmaster exhaust but those are the only mods I've done. Just wondering whats to much trailer especially for the tranny! Thanks for your input!

 

Biggest i've pulled when i was stock(5.3 and 3.73s) was a 30 foot tag a long. Didn't really like it but pulled it decent in tow haul mode

 

I tow a 31 ft travel trailer with my truck but that's meaningless due to the number of variables that apply.

For example, these are the specifications I had to consider in my choice of travel trailer:

truck specs -
2012 Silverado 1500 2WD EXT CAB LT (standard box)
VORTEC 5.3L V8
6-speed AT

trailering package

integrated trailer brake controller
18' aluminum wheels
on/off road tires

CAT Scale weight with full fuel, truck cap & bedrug 5440 lbs

available payload 1360

GCWR 15000 lbs

Your owners manual is a good place to start in determining the capabilities of your vehicle.

Good luck.
