Many people who want to add a small camper to their pick up truck discover that there are very few lightweight travel trailers to choose from. Weight is the problem not the variety of the RVs, since most of the existing recreational vehicles in the category are too heavy for a car or light pick-up truck to pull. Moreover, a closer look into this matter will convince you that even the RV companies whether we are talking about rental agencies or dealers are reluctant to purchase lightweight travel trailers to keep them on stock. The reasoning for such a sales policy is very simple: the demand is lower for such recreational vehicles, and therefore it is not efficient to keep them in stock.
