There really isn't any downsides if you are using it for what you intended to... hauling your camper... or other large items
We have had a big, long crew cab dully for nore than 10 years... Janet drives it with the camper on... she'd never drive it with the camper off (then it feels big)
I drive it anywhere, any time... but it was never meant to be a grocery getter at 15.1 mpg camper (loaded)... a little better empty.
We have a 2008 Toyota Prius (54.6 mpg) for Dr visits, groceries, etc... it has never been more than 50 miles from home.
If you have learned how to easily load your TC then why would you have trouble parking or driving on a street?
We have driven our TC loaded dully on every street in the French Quarter in New Orleans with no problems.
We usually park "out" in the parking lot weather we are in the Prius or in the GMC dully when we go to crowded places... or even when they aren't crowded... in our Prius and in our dully... I don't like the unskilled drivers hitting my vehicles with their doors.
So, if you know how to drive... it really won't make any difference.
The circles that you drive will be a little bigger than you would be able to do comfortably with your auto or a smaller truck... some of ours have been more than 6000 miles and took more than 6 months. :W
You will enjoy it... like you have enjoyed what you have now...but you'll actually have less limitations.
Sleepy
BTW... how often do you drive through a bank of fast food... (we don't even in the Prius)
WE got excellent millage on the tires... the total weight is distributed over more contact area.
