pianotuna has a good point. Many RVers have older units but have kept them up well and have reliable Rvs. Cheaper is not necessarily a better deal. A 5 or 6 year old unit should be reasonable? Personally, as one who has lived in 30 countries and moved 42 times--I distrust public facilities mainly due to unseen hygenic issues. I spent 3 weeks in a hospital with a neuro/eye-related virus from a dirty CG facility and another 3 months recovering. I prefer a small toilet/shower in a B to almost any CG alternatives. If this sounds odd, then relive my 40 years in places like Iraq, Ethiopia,The Philippines,European locations, the Caribbean, Central AMerica, Asia(14 years) and so on, with the exception of Japan(8 years) which was incredibly clean, ryokan,hotel etc wise.
