So you've ruled out camping now? What caused your change from planning on this idea to sounding like you're disgusted by the idea?

If I understand you correctly now that you are planning to take one month traveling from PA to Denver and you've got just $3000 for this to happen.

If you are staying in hotels at $50 per night (did you factor in room taxes and pet deposit fees?) you're looking at $1500 just for lodging. You haven't said what you are using for transportation or where your route will take you, but a real rough estimate would be another $500 for fuel. That means you'll have about $1000 left over to live on, so if you kept your food and other expenses down to $15 per day (which would be pretty spartan) that would leave you with about $500 left when you get to Denver.

I suppose the next question would be, what do you plan to do when you get to Denver?

As far as bumps in the road, well I'm sure you'll run into at least a couple, but bumps in the road and other unexpected things are what make roadtrips (and life itself) interesting and unique adventures. If you want perfectly smooth, you should look into taking a guided tour where every step of your day is planned out in detail.
