#1 TT  190 Laminated w/ Aluminum frame wall
22 ft 5 total length. Ext Height 9 ft 10 in.
Gross Weight 5500 lbs. Dry Weight 3620 lbs. Cargo Weight 1880 lbs
Hitch Weight 525 lbs

#2 TT 190  Stick and tin
21 ft 6 in total length. Ext Height 10 ft 6 in.
Gross Weight 7415 lbs. Dry Weight 3810 lbs. Cargo Weight 3605 lbs
Hitch Weight 415 lbs

Both have dual axles.

What would make #2 TT Cargo weight capacity 1800lbs more than #1 TT ?
Is it the construction ? IE.. frame, axles, etc ?

 
Basically frame, axles and tires chosen for it. Skimping on weight carrying capacity is one of the common methods of cost & weight reducing an RV without sacrificing the eye candy. A sturdier frame carries more and be more rigid (less of the twisting that opens seams). So-called "lite" models may achieve their lower weight by reducing chassis capacity.
 
Why is the hitch weight cap. more on #1 trailer ? 525lbs
By that, Im assuming #1 can handle more weight at the hitch end.

If #2 is made more "sturdier", why isnt the hitch wt more than #1 ?
 
Both of those hitch weights are a fiction - basically the weight on the hitch when the trailer leaves the factory. It is not a rating, so has nothing to do with how much the trailer can carry.

Your actual hitch (tongue) weight will be 10-12% of  the loaded trailer weight. It has to be for good towing manners, i.e. no sway. The weight can go higher than that if the tow vehicle can handle it, but 10% is considered a minimum.
 
I note the "dry weight" of the two trailers is fairly close.  This is how much the EMPTY trailer weighs.  They are probably similar build quality, but one has heavier axles and tires capable of carrying more weight.  Thus a higher GVWR and payload.  What Gary said.

As Gary said, published hitch wt is fiction.  To tow comfortably, you need at least 10% of the total trailer weight on the hitch.
 
The fact that the #2 trailer can carry 1800 lbs more, both TT being somewhat the same layout, can one assume that #2 is a better constructed TT ?
Both are about same yr 2006/2007.
 
"Better constructed" covers a lot of territory.  A greater GVWR pertains mostly to the trailer frame & axles, so the construction of the rest of it may or may not be better. Generally, a model that includes better running gear also has "better" in other areas simply because it is designed to a higher price point, but that's conjecture until you get down to specifics.  It's conceivable that #2 simply spent money on the frame & axles to obtain the higher CCC rating, but skimped elsewhere to make up for it. I note that #1 has the more expensive laminated fiberglass & aluminum wall construction while #2 has the less expensive "stick 7 tin" construction. Most people would say that #1 is better constructed as far as walls are concerned.
 
Ok. I thought composite trailers were more of a throw away item than stick.
When there is damage, assuming they are more of a problem to repair.
Lets face it, low price 8,9,10yo TT are going to have issues.

I did a quick load rate.
Includes, hitch&acc. propane tanks, battery, 1 passenger, full tank gas and the TTs dry wt.
No water, no food, clothes, tools, etc.
Vehicle tow cap. - 5800
#1 TT- 4122
#2 TT- 4312

About 71-75% of vehicle tow cap.
Drag coefficient. #1 TT front is much more angled than #2 and has a smoother skin.


 
Both sidewall type are repairable - just need different techniques. The perceived quality difference is that metal frames don't rot when the inevitable water penetration occurs. That's a plus, but laminated sidewalls often delaminate when they get wet, whereas metal siding does not.  So there are pros and cons to each. One could debate the choice at length!
