the factory towing package (HD radiator, engine oil cooler, HD tranny cooler, and receiver hitch), the late-model Town & Country cannot tow more than an empty rowboat. With
the factory towing package, it can tow a trailer with a wet and loaded weight of not more than 3,600 pounds.
2012 Town & Country:
3.6L V6 24-Valve VVT, 6-Speed AutoStick Transmission, Towing = 3,600 lbs. max.
Only a very few tiny bubble-style TTs have a GVWR less than 3,600. And they would be even more cramped than your mini-motorhome.
So forget TTs and look at fold down RV trailers, a.k.a. camping trailers. My RV trailer was a Wheel Camper camping trailer all the years my kids were at home. We camped all over the USA, from Maine to California, and from Washington state to Florida, and just about everywhere in between.
Here's one with GVWR of 3,000 pounds, and includes a minimal "bathroom".

Forest River makes a wide range of camping trailers, including some way too heavy for a T&C. Here's one that is less than 3,600 GVWR:
