A note on axle capacity (YOU MUST CHECK, THIS MAY NOT BE TRUE FOR ALL YEARS NOR MODELS).
My axles are rated and labeled by AS as 5000lb Dexter Axles.
I called Dexter with the label info, just to get common maintenance part numbers, as there is no 5000# axle listed on their website. I was told that there is no such thing as a 5000# axle and mine were 6000# axles.
NOW!!!! Just like your TV, that does not mean I can just load the cart, as I please, up to 12,000#s on the axles. There may, and probably are, other "system" reasons for AS to rate the max axle loads to 10,000#s. And in fact when you consider TW, and AS GVW, you can't. (or shouldn't, depending on your perspective).
All this, in the last paragraph, is reflected on the sticker on my closet door.
It is nice to know I am "over-axled", but has little bearing on my load capacity. All that said, at last weigh, I was at about 7600# on the axles and 850# on the tongue, for a total of 8450# without water, fully loaded for camping. GVWR is 10,000#s.
I need to do a reweigh next spring, to see how much weight I've gained since last weigh, in 2011. They are sneaky in gaining weight.
