(another) New Trailer

As Eric knows, last night I sold the trailer I just bought (for the same price). Now I'm planning to buy a new one. And get the order in asap so I can get cracking. Here are the specs:

• IRON PANTHER 7X16 TANDEM AXLE CAR HAULER 7000 GVW
• 7x16 Carhauler
• 10000 lb A-frame 2 5/16" coupler
• A-frame tongue
• 2000 lb tongue jack (bolted on)
• DOT approved safety chains w/hooks
• DOT approved lighting system
• 7-way RV plug with loom
• Breakaway kit
• 5"X3" angle frame
• 6" high front bump bar
• 4' angle ramps
• Stake pockets
• 83" wide inside deck
• 2" treated wood flooring
• 3500 lb easy-lube axles w/brake flange
• 1 electric brake axle
• 5 lug 15" wheels
• 205/75 15" tires
• 7000 GVW
• 5600 lb payload

I will ask for it withOUT:

• 6" high front bump bar
• 4' angle ramps
• Stake pockets

I'm also considering asking for it withOUT the fenders (since I can the wood framing will go around the wheels and I can line it with an aluminum flashing---although building over the fenders might be better?), and withOUT the treated wood deck since I'd rather use untreated wood, and each thing I leave off the list, the cheaper the price becomes.

Remaining questions:

• Is a bolted (rather than welded) on jack ok?
• "7-way RV plug with loom" Is this the round plug that links the truck's electric with the trailers?
• "3500 lb easy-lube axles w/brake flange" Good?
  
• "5 lug 15" wheels" Good? What ply are these?
  
• "205/75 15" tires" Good? Sufficient max load?
  

Just an update.
Thanks!
