Brand New - looking for advice

thanks for the great input. Sounds like I just don't have the tow vehicle to get much and a tent trailer pop up might be the best option. To clarify - 3 kids, still relatively young so really the rv would just be for sleeping. Would something like this not be possible to tow? Kids would probably be happier in a tent outside anyway....
