Upsizing an axle....?

Hi all. Newbee here and with all the reading I've done on this site I haven't found an answer to a question of up sizing my axle. It's a 64 19' Globetrotter that I'm doing a frame off renovation/remodel. The registration say it weighs 2900# and the axle is rated at 3500#. It needs a new axle anyway and I don't know how much weight I'll end up with when finished. I don't think I'll add more than 600# but you never know. When it's finished and ready for travel fully loaded with gear I'm thinking it will be 3500# or better. Should I be concerned that I'm at the threshold of the 3500#? Should I go for a larger weight axle?
Any comments or thoughts on this would be greatly appreciated.
Thanks GRM

10% or more of your trailer weight is on the tongue and not the axles. Also the weight of the tires, wheels, brake components and some of the axle itself does not count because they are not supported by the axle. You have more capacity then you think.

If you haven't started yet, get yourself to a weigh station and weigh it as is. You don't know if the registration weight is the actual weight, or just the dry weight when it was sold back in 1964.
You might already be at 3500 lbs with just your dinnerware and linens. You'll be able to calculate all the add-ons easily (Gray Tank? Microwave? Propane? Cork Floor?) and you'll know if you want to go up in axle capacity.

Is there a reason you can't do all of your renovation and save the new axle for last? You could then determine just what axle you want. Changing an axle is no big deal.

I would echo the posts above. You have to know where you are in order to get where you want to be.

Weigh the entire trailer in full dress towed application before making a decision based on trailer weight.

"I'm thinking it will be 3500# or better" doesn't exactly work on the road if your thought process is in error.

Thanks guys for all the feed back. Sound advise from all of you. While I was waiting for some responses I stumbled onto another thread of New Axles and got some info off it. I've got a lot to learn in this new project I've created. Glad I found this Forum....

Keep in mind that the axle does not have to carry it's own weight or the tongue weight. So don't over do it. Too heavy and it will beat the trailer to death.
The tires and rims are what carry ALL of the weight minus the tongue weight.
