Help! Newbie campers need help picking out a TT and TW

Would something like this work if we bought it?:

It's older but has low miles.

We figured our current Suburban isn't going to work. If we can buy a used vehicle for towing that is relatively inexpensive, we can just buy a used rv as well (the one we were going to buy was new, had all the bells and whistles but was $$)
