Trip around the USA: I'm new to it. Help!
I'm planning out a huge roadtrip for the summer of 2019. I'd really like to see the USA, but I am a minimum wage worker so it will take me some time to save up. I have the route plotted out. 11000 miles over about four and a half months. I'm taking plenty of time in each location to really take in the sites. I'm also breaking driving up into about four to six hour days. Is this a reasonable way to do it? Can I go more? I've never driven quite that distance in a day before, but I love to drive so I'm not too concerned about it.
My big concerns are the cost. I have camping gear and plan to camp around the national parks and stuff, but what's the cheapest way to stay in the cities? I've heard about couch surfing, but are there any other good ways to do it?
My car will need to be replaced before I go. Would it be better to get one that I know I'm getting rid of when I get back home again, or should I look into renting for the trip? Or should I look into getting something new?
How do you guys tackle eating on the road? I've got some ideas for breakfast and lunch, thanks to a cooler and ice (I'm diabetic and need to keep insulin chilled, so this was an absolute MUST.) but what about good dinner ideas? I won't have access to a kitchen all the time so I have no clue how to tackle that.
There are lots of attractions and museums and zoos and aquariums I'd really like to get to experience, but they get pricey. I'm definitely getting a pass into the national parks (I'll be visiting about a half dozen of them) and I've seen that some places, like Seattle, have passes for those kinds of things. $75 for $120 worth of admission or stuff like that. Do you find that lots of cities have that? Or should I just budget a bit more for those kinds of things?
I am budgeting for laundromat trips, repurchasing toiletries and things (though I might just stock up at a Costco or something before I go), gas, campsites or motel rooms, and buying food at grocers instead of fast food or convenience stores. Anything else I should be budgeting for?
Basically, I could really use any tips you guys might have. Any gear I should look into that you've found helpful? Spots around the US that are a must see? Wish you had spent more or less time somewhere?
Thanks for reading this, I appreciate it.
