I am considering purchasing a new 700-4 as it will fit perfectly into my storage space. the 1000-5 is too large for where I need to store it. My only concern is will the 700-4 have enough power for the steep hills near the Smoky Mountains. We will only use the 700-4 on paved roads in our neighborhood and on the county roads in the area but some of the roads near our cabin are pretty darn steep. I feel like it would do ok with just two of us on board but what happens when we have 4 people on board? (My wife and I and two 17 year old boys.) Any thoughts on whether or not the 700-4 can handle steep pave roads? Thanks in advance for any advice that you may have.
