Good morning Lonb, You should add a signature so we can see what you have. I can only assume its a 29HFS and by the weight I can assume you have the Extreme Pk and the generator. What does your sticker say is the GVWR? What is your rated cargo capacity?
Many forget that besides the trailer's axles, it is important that 10% to 15% be carried by the truck as tongue weight; that said, your 4400# axles can, in theory do the job, but I am also sure two 5200# axles would be enough; any higher is unnecessary and might not be compatible. I will explain. No matter the capacity of the axles, you can not exceed the GVWR. My sticker says 10,985#. I would think your's is less??
Lets add it up using the weights you mentioned: with garage at max (2000#), plus 500# in water, plus 500# in other stuff (clothes, food, pots and pans) you will be around 10,400#. Keep in mind you cannot exceed the GVWR. Water in the tank offsets some of the toy weight which is a good thing for maintaining a higher percentage of tongue weight and maybe half of that is on the tongue. 52 gallons of fresh weighs about 448#, BTW. I will assume you don't haul black or grey water around for any distance.
Based on that total of 10,740# the minimum of 1040# should be on the tongue, which leaves 9700# on the axles or 4850# each (exceeding their 4400# rating, but well under 5200#). If you could somehow load it so you have 1500# of tongue weight that would leave 8740# will be on the axles or 4370# each, slightly under the ratings of your axles.
We cannot know without weighing what each axle is really carrying and it would be better to know for sure how much each wheel is carrying. Not saying it is an issue without weighing, but each wheel on the trailer will be carrying a different weight.
Frankly, I would feel better with E-rated tires and wheels. But by the math, it isn't necessary.
Also, the axle, tire, wheel ratings take into account reasonable driving hazards, such as bumps, dips and dives.
