Every RV type is a matter of finding the one with the most pros and least cons and that will be individual.
With a truck camper, yes, you would generally be taking your "camp" with you everytime you want to drive somewhere. If that would be a problem really depends on where and how you will be camping.
If you are setting up a base camp and then taking a bunch of day trips, then the TC is less than ideal unless you can tow a small car or scooters, etc.
If you are doing a lot of one night stops until you reach a destination and then staying place for a while (no day trips), then it would be a good choice.
Some folks use a TC to sightsee, however they might park it at the RV Park and use uber, public transit, etc to get around.
You just have to decide if you can work around the negative of a TC in your personal circumstance and if those workarounds are easier than any inconvenience.
