Good question! Our two cents for your consideration. May want to post this ?? in the Paradigm forum to get other existing 382RK owner input quicker.
We have just put an offer in on the 382RK and will get our trailer in mid-late Feb. We are full timers & have been lurking on this site & “ shopping” various 5th wheels ( our first) for@ year or so & joined the forum after we had narrowed our search down to 3 mfgrs. this forums members have prove quite knowledgeable, willing to help, and patient w questions.
In our experience, suggestions from forum members, & discussions with our dealer, their service department led us to be able to meet our Alliance Area representative in The Portland RV show this last Nov . Who put us in contact with the Paradigm techs. Were told that the Paradigm frame, suspension & 5th wheel pinion have been engineered to mitigate the added rear weight the RK loading creates. Was advised there is added framing to help reinforce these support spot loads.The Paradigm underwent a major design revamp based on owner feedback tto remedy very early issues.
We also queried how they have solved the waste tank support & were shown added Tank supports for the black & gray water tanks.
Suggest you contact their Customer Service,,,they are responsive & have proven to us they are truly determined to do what is right,,,listen to thei owners,,,and stand behind their products and their dealers. While we will be full time on our property but are quite pleased w Alliance’s comittment to doing what is right. Hope this helps,,,we encourage you to reach out,,,feel you will not be disappointed in their efforts to answer your questions,,,Other RK owners will probably weigh in as well with their input,,,this forum is a very good resource,,,,Safe travels,,,Enjoy your Holidays, & safe travels! 👍🌞🍀
