1. Because Fifth wheels can be so large, how hard is it to find RV spots?
Sorry, but it depends. I tow a 38 ft, you adapt. Secluded lake in boondocks, difficult. Urban areas... easy. It is not as difficult as you may think.

2. Related to the first question when looking for RV spots I noticed that it is based on length, is that the length including your towing vehicle or since you can detach it, is it the just the length of the fifth wheel?
Most sites ask for length of trailer, but allot for tow vehicle parking.

3. Is a fifth wheel size worth it? I have been told by a few people that it might be too large for me. I haven't had a lot of experience driving super long vehicles, but I am a bit stubborn and when someone tells me I can't do something I like to take on the challenge, but also wasn't sure what a realistic expectation is or if I should be considering something smaller.
Driving and towing are a learned skill, if you have never towed, find a mentor or a driving school. School of hard knocks can be expensive. If your towing skills are up to it, find the rig that fits your needs. The avalanches are nice looking units.
