This is based on my own experience and opinion...I'll also admit to being a huge Jayco fan after having owned 7 new Jayco's so far...from tent trailers to our current (bought new in 2003) Jayco Jay Flight 5th wheel.
Not a single issue or re-occuring issues, and we didn't note any problems due to quality control or inferior build.
Jayco is the 3rd largest RV Manufacturer in the World, been in business owned by the same Bontrager Family since 1968, made profit everyone of their 35 years, consistently wins the Gold Circle Quality Award, makes all their own cabinets, beds and furnishings themselves, and have a terrific factory tour! ;)
PLUS Jayco has a industry leading reputation and 2 year bumper to hitch warranty!
Jayco's RV's are made with high pressure vacuum laminated roofs and walls (not glued and pinch rollered!)...it takes more time to make them this way..but are 10 times less likely to delaminate (bubble) due to leaks.
There are few (and I mean very few!) other RV builders that also have done extrodinany things for owners too, and I give them high 5's too.
But I vote with my loyalty, and we are very close to placing an order for our #8 Jayco! :)
Just my humble, unbiased and freely given opinion! And no I don't own stock in Jayco either...it's not publicly traded! LOL!
This is the very first Jayco RV made by Lloyd Bontrager. (Jayco 1968...)
Good luck! Do your research and look inside, under and around any RV before making a decision. Look for name brand equipment instead of brands that make you say "huh?" Real wood or heavier more prone to falling apart when wet particle board? Plastic fixtures or plastic? Many brands will void your warranty if you full time in your rv! Read th warranty. Jayco does not void for full timing.
