I say sure you can do that, I however, would maybe be looking into finding a place to stay at
when I hunt Ohio, its a 7+ hr drive for me, first started going ended up in hotels and then found cabin near by, that made the hunt that much more enjoyable
became very good freidns with the cabin owner(let me stay for free a few days every yr)
but the ability to take a shower and try to stay scent free, makes hunting more productive I say too!
so there are perks to having a shower, even if it costs a little extra
but get the budget is what it is, and have to work around what you can
I also found that when I drive far, I try my best to make longer satys happen too, , to justify the costs of gas and time getting there, most my hunting in ohio had been 7 or 14 days stay's too
so, that long, the cabin came in very handy, say if it rained or, got really cold
