This is an excellent suggestion. Just be aware that toy haulers are build with much heavier frames, suspension and the coach body is heavier too, plus larger fresh water and waste tanks. This will drive the dry weight up and the manufacturers will increase the GVWR accordingly. End result is, even with a fairly small toy hauler, you may need a more substantial tow vehicle than with a comparable ordinary TT.
This thread gives some consideration to toy haulers and issues.
The nice thing about a toy hauler is that they are usually better built, and on the used market tend to be lower priced than you expect as specialty stuff is a harder sell and people just want it gone.
