You may or may not reach the trailers max GVW. All depends on how much stuff you put in it!! Do you know what the load figure of the trailer is as built, or one like it? Just using the "sales" weight figures show aboot a 1670 lb carry capacity. You probably will be very near the max if lots of food, clothes, and carry a full water load. At that weight, your Expy should ok, but won't set any speed records on hills. Only engine back then was the 3V 310 hp 5.4L V8. Axle ratio will also be involved as to towing weight and ease.
My combo is somewhat near the same as yours may be, with 4.30 axles, our Excursion and our max GVW of 9200 for the trailer is right at the top of the factory figures. We do well even in the mountains. The V10 is a pretty good puller esp when running in the higher rpms needed. Your V8 will rev pretty good also keeping speeds up on hills.
Not to knock your choices, but as a first time buyer, maybe a smaller unit would be a better idea. Or, rental to see how your tow vehicle does, and how you do also!! We started around 19ft years ago, and have slowly moved up to our present 34ft "monster".
