Not sure that I can add anything that has not already been discussed. We are 26ft, traveled cross the USA and through a number of Canadian Provence's without a toad. Like others we seldom use all the hook ups. Mostly just electricity.
We often have to walk a way to some attractions/restaurants if in a congested area. But that is good for us so no complaints. If we are near a large city we often take public transport to attractions. Have meet some enjoyable local people who have provided addition information on places to see or good restaurants, or easier ways to access popular locations.
It really depends on your capabilities and how you enjoy traveling and seeing the sights. Occasionally we will pull a scooter big enough to carry the two of us and that is a fun way to get around as well.
Enjoy.
