Trailer falls within your truck specs
Since the spec sheet you included had a VIN I presume it is a built trailer - ask the dealer to take a photo of the "sticker" on the trailer that shows the "actual" weight of that trailer - vs the Mfg. generic specs - be sure you know what you are getting - mfg. weight for shipping - sticker should be on trailer (see example photo).
You will want to add a WD hitch - like a weigh safe - to help offset squat and control sway - link

Trailer itself - is heavy empty - 2,1xx cargo capacity is not that much - can use that up pretty quick.
Water - 40 gallons is very limited - would expect in a trailer that size 80 gal +
Gray - 39 gal - pretty typical
Black 39 gal - pretty typical
Not a lot of water - unless you are always at a RV park with water and dump on-site, so you can cycle water quickly - for dry camping that is good for a two days with a full trailer at best - or no showers!
13,500 BTU is not enough 15K BTU is better but trailer that size needs 2 units to be comfortable in warm weather - Know it is ducted?
8 cu ft. fridge - ok for the weekend - but for week or longer is small - even going 10 cu. ft. helps
6 gallon water tank - small - 10 gal would be better for larger trailer - also always look at pump flow rate - how many gallons per minute is flow - 3 is typical with water heater
30 amp vs 50 amp - on a trailer that size I would want 50 amp - especially if you plan to add solar and another HVAC unit.
Insulation - not noted - be sure you know what your are getting - R7 in walls etc - keeping you cool or warm pending outside weather
Total length - 38' +/- - long for a bumper pull - I prefer a 24' to 28' trailer - which will be 30' - 34' overall length - just much easier to manuever - over 30' I would prefer to move to a gooseneck/5th wheel - they trailer much better than a bumper pull. But with your truck pin weight may make that not feasible.
