This tracks exactly with what I saw when delivering RV's (trailers) for Horizon Transport and the Industry press I have read.
The takeaway here of course is this is the perfect time to drive a hard bargain for a TT or 5th wheel.
Of course anyone who has traveled across this country and seen for themselves the multitude of RV Dealers who have literally hundreds of units on their lots. That is just not sustainable. Right here in Tucson for instance there is a cluster of dealers in S. Tucson all in the same two block area and each has between 100 to over 250 units on their lots...most of them 2018's
The first question I ask anytime I go looking for a new trailer, and asked in an offhand way, is: " How many units do you have on your lot"
They often don't want to answer this but I find a way to ask again before I am willing to talk about specific units. The answer I have gotten most times was between 200 to 400.
This level of inventory is a huge financial burden on them and when I ask that, then I follow up with my guess about how much money that represents... I am usually very close.
This puts them in a disadvantageous position when I start to negotiate. (I am currently looking for a 40+ft 5th wheel)
So if you want a trailer especially a larger one get out there now.
