Personally...... I'd get a lockable key box, bolt it in your truck somewhere and keep the rental keys in it (as you suggested). About the seven (7 for the dwarf lords in their halls of stone.. sorry, LOTR nod there).. Do you really, really need to carry all those? Why not hide the ones you need after you get into the house? Do you abduct people and keep them in cells? ( I swore I wouldn't ask, but 7?!!) OK, I'm calm. They're your keys you carry them how you want. . I'd be tempted to drill them and put a bolt or a shackle through them. There are special EDC things (I.e. expensive) that will let you put keys together like that, Cornys got one from BAMtactical but I can't be arsed to find the link.

"Is it mailed? Did you mail it? Where's the tracking? I'm pretty excited. I hope he cries. Think he'll cry? What a bitch."
"Q is an asshole, but he's so dumb I feel like hugging him all the time."
"I'm waiting for Digiorno to cook. Three meat, stuffed crust. It's not delivery, but no place delivers here. So. "
First, I love that you've made your own. (In a way I think that this forum is kinda the place to be "doing it yourself"), but I just saw this, and what caught my eye was the mention of "optional expansion sets". As I said, you've got your own (superior one) now, but anyone else out there who's following might be interested.
