ladder stand recommendation

That's fantastic news! It must be great to have your son, a USMC Sergeant, join you for hunting. For a two-person ladder stand, you might want to check out the Millennium L220 or the Rivers Edge RE651. Both are known for being comfortable and sturdy, with shooting rails and heights in the 15-20 ft range.

The Millennium L220 has a wide platform and comfy seats, while the Rivers Edge RE651 is great for its stability and ease of setup. Either of these should give you and your son a great vantage point for your hunt.

Happy hunting!
 
I will say this. Ladder stands of today aren't nearly as heavy built as they were 4-5 years ago. I just bought a single man stand. It is a piece of crap.
I would look a lot at different brands. Like said above look for large foot platforms, and braces that tie the top to the foot platform and down to the ladder if possible.
