Can the below setup safely pull?

We have a 2011 27' zinger.
dry weight 4702 pounds
GVWR 7482 pounds
GAWR 3500 pounds
Cargo Carrying capacity 1110.39 KG with fresh water tank full.

we have a 2008 Chevy Silverado
5.3L Engine
3.73 Axle Ratio
GVWR 6800 pounds

according to my book the max trailer weight should be 7,700 Pounds.

we also have a weight distributing hitch with sway controle arm.

In terms of straight line pulling trailer should pull okay with your truck. The 3.73 gears and 6-speed transmission should keep the 5.3L right in it's power range.

The one gotcha could be the 6,800# GVWR of the truck. By the time you fuel up the truck and put people in it, you'd be very surprised how little available cargo capacity you have left for the trailer tongue weight. With your trailer you can probably figure somewhere around 1,000# of tongue weight.

Make sure you know that the WD hitch DOES NOT remove tongue weight from the truck. The only job of the hitch is to transfer weight from the rear axle to the front axle so that it is evenly distributed. So, with that you will most likely be driving your truck at maximum GVWR when pulling trailer.

I don't see any problem with this. Simply make sure everything is properly connected and drive carefully down the road as you enjoy your RV.

If the TT's dry weight is 4702 from the brochure then add 2-300 lbs to it. So roughly 5000lbs delivered, then add about 1000-1100 lbs average for 2 people with a decent amount of stuff loaded. So your in the 6000lb loaded weight range. Figure around 12-13% for tongue weight. 750lbs. Now look on the drivers side door for the yellow cargo sticker and see what it says. That is your max cargo rating. Subtract your 750lbs from that and what you and whoever else is riding in the truck along with whatever else you think you will carry in the truck from that number. That will tell you if you have enough payload capacity. The best way is to load up the truck as if towing and get it weighed and see how much weigh you have left for the tongue. GVR of the TT is 7482- 5000lbs is 2482lbs, doubt you could load that much into your TT unless you have a bunch of kids or a toy hauler.

From your numbers provided, you certainly wouldn't be under your tow rating if towing the trailer fully loaded but that really has nothing to do with safety. As long as you're not over your GVWR or GAWR there is no reason it could not be SAFE. Now keeping your warranty in effect might be the issue you'd need to look at if you go over your tow RATING because tow ratings have nothing to do with safety, just reliability.
Good luck / Skip

Should be acceptable. 2008 + 3.72 means 4-spd, so acceleration may not be great, but it will tow at 65mpg all day long in 3rd gear.

If I were going to travel over hill and dale, ie; across the rockies, or really pound the pavement from coast to coast, I probably would go for a little more of a margin. Most of us are weekend travelers who take occasional long trips. If this is you, I'm sure you'll be fine with the combo you have. Either way, travel light and leave the dumbells home.

We are not to the point yet for the long trips as we are still new to pulling TT. most trips right now are just the with in 100 miles and the majority of those are less than 100. would like to take it from NW Ohio to Kentuky for a week to see out son in the military.

The WD hitch DOES remove tongue weight from the truck.

Let's assume the tongue weight is 750#.
When the ball is placed on the coupler, a load equal to about 1100# will be added to the TV's rear axle.
A load equal to about 350# will be removed from the front axle.
The full 750# is carried on the truck.

A properly adjusted WDH will restore all of most of the 350# to the front axle by removing load from the rear axle.
In the process approximately 175# will be transferred to the TT's axles.
The net load added to the TV's rear axle will be about 575#.
And, the net load carried on the truck will be about 575#.

For this example, and for many real TV/TT combinations,
the load added to the TV, after application of WD,
is equal to about 77% of the tongue weight.

We tow our 31 ft Kodiak (loaded weight a bit under 6000#) with our 2009 Chevy 5.3 liter, 3.73 axle, and 4 speed automatic. The Chevy does a very satisfactory job but I CANNOT tow in overdrive. If in cruise control and in a pretty good uphill tow, it'll shift from 3rd gear to 2nd. If I cancel the cruise before starting uphill, it normally will not shift to 2nd. I think you're good to go.

So to sum up it sounds like you will be ok for limited driving distances. For me the silver lining is that you can justify getting a new truck sooner rather than later if you want or just hold on to what you have for a while.
