Nu Chevy Express Van 4.8 or 6.0

Hello fellow carpet cleaners ! About to make the big leap into a new Chevy Express Van 2500. The question is I am buying two of them one that I will be transferring my current entry cleanco charger and the other a new Bluewave and am wondering will the 4.8 liter do the job or go with the gas guzzling 6.0.

I am one that had to learn the hard way and do this twice reason I had purchased a Chevy Astro Van 2000. After a wheel falling off on the freeway , Trans needing rebuilt and suspension upgrades it is time to move up and do it right the second time.

Thanks for all the great advice I should have listened!!!!!!!

Thanks Doug! You da Man!!! You usually have a one liner to go with it too cold out there?

One ton van for the slide in for that big Bluewave

Second van just have a entry livel Cleanco Charger light weight which will be the 3/4

Therefore the v8 4.8 liter is ok for both then right

This is great info Mr. Steamer and Doug. Do not want to do this a third time. This time I need to use this info from experienced people suh as you guys who have been in the game.Your honest true inputs. Sensible and realistic.

Therefore my decision will be the Chevy Express 3500 with 6.0 Engines and not to look back. Less wear and tear and which has the power if needed.  Thank you !!!!!!! 

Whow! How does this compare to what I am about to spend 18k on a new Bluewave. Three thousand dollars. Is this machine all that.
