I'm not interested in a "off road" trailer, but a popup or hardside trailer that has a water heater and a fridge.

I know there are some light ones out there - anyone have a particular model or year they like and or have experience with? Old is fine - I'm looking for a cheap place I can sleep, shower, and $hit until I get another RV. Obviously I'll be running a porta potty and an external shower, but a water pump and water heater are a requirement.

I'm towing with a TJ so around 2K is my weight limit.
