Many on the forum have done the "axle flip" on their campers. There is nothing special to the T2570 that would make your different then other floor plans in the same weight class camper.
Your camper should have qty. 2 3,500# axles, (7,000# GVWR) is that correct? If so, that should be a 2 3/8" axle tube. And yes they are what we call a "drop axle"
Here is the kit Tod is talking about. Scroll down to the "K71-384-00: Over/Under Conversion Kit"
Heads up, make sure you get the 2 3/8" tube kit and not the 3" tube kit as the 3" kit is for larger axles and will not work on your smaller one.
Here is link to Etrailer with a lot of great pics of this over/under kit installed on a drop axle. https://www.etrailer.com/Accessories...71-384-00.html
It is actually an over, under switch and not really the nickname, "axle flip"
When I buy Dexter parts, I check at least these 4 places once I know the part numbers I'm looking for. Some have free shipping, others you pay. So it is out the door cost. I have had good experience from all these suppliers. They are all neck and neck on cost. Some local trailer parts shops may have the kits too.

Here is one of many links on Sunline club doing the over/under conversion, in this case on a cargo trailer but is has good pics that will be comparable.
There are 2 things to realize with all the height gain.
1. Odds are high you will need some kind of extra entry step into the camper. The jump is sort of too much without it.
2. You will have to readjust your WD hitch and may have to get a new hitch shank to account for the added height.
I think in no. 2 you are asking in the towing section on getting a WD hitch, so when that comes up, let us know as it could affect with WD shank you get.
Hope this helps
