I was pretty lucky. Didn't know it at the time but found out later.
We went from tent to trailer because... we got one of those raining periods that happened to be our vacation time. And I could only sign up for vacations in Jan at work. How do I know what the weather will be like in June?
As we were laying in the tent listening to rain fall wife said we could afford a trailer. Measured out how long campsite was (in the mud)and measured our truck and said we can get a 25 footer and still fit into the campground.
Next day took wife to RV place and told her pick out anything 25 feet and under. Of course she was pleased with "HER" RV. She picked it out!
And we used that trailer for 12 years and have many fond memories of it. Still miss it.
Like I said I was lucky. Very lucky.
Here is why. That is not the way to buy an RV and could of cost us a lot of money. Read some on this forum and you'll learn a lot.
Wish I'd known about this forum before we bought. We were lucky!!!
