Welcome to the 815 club. Mine wet and loaded weighs 2,400# per CAT Scale, only option is the air conditionerkl. I've had mine since 2009 and haven't had any issues.
If you can't find a set of pods, I would suggest you make a set of brackets to hold tail lights at the rear of the camper and plug into the standard 4-way plug on the sides of the camper. The truck lights may be hard to see when someone is close to you. If you would like to see what they look like, I have a set in my shed.
Hope you know the shower drains into the black tank. Some folks change the shower drain to a hose so they can catch the water in a bucket and either pour into the sink to put it in the gray tank or carry it to the shower house.
At least you have a mattress, my first night in mine was without a battery, no power, no mattress, no water except for the gallon jug I had bought in a Walmart. Had to sleep on the dinette and I was so tired I didn't even put the table down, just crawled in under it.
If you need any info about it, just shoot me a message. I've made a few mods to give more space like a pull out pantry under the fridge, shelf over and beside the entry door along with a cubby behind the monitor panel.
Hopefully, you will have as much fun in yours as we've had in our.
