Q: Will this base fit with the swivel used in the new Winnebago Solis Pocket? The van is on the Promaster 1500 chassis but not sure what swivel they have used.

Asked by: Jimmy S - 9/3/2022

Asked by: SC - 11/16/2022
A: From DETstru on the Promaster Forum: The Webasto Air Top 2000 STC easily fits under the Sportscraft steel lowered seat base (bought from Eurocamper). My setup has: the van steel floor -> the included +\-1" Webasto rubber/foam seal -> a 1/2" thick plywood spacer I made myself (should have made it 3/4" or even 1" but may have needed longer M6 bolts) -> the included Webasto steel mounting plate -> the included oval shaped Webasto rubber gasket -> Webasto heater.

Q: I assume these will work with the model of Promaster swivels that you use to carry in 2021? (Items ID 3370091 and 0092-US at the time). Thanks

Asked by: Martin J Brown - 2/3/2023
A: This is a lower version of the standard seat base. Most any swivel that would bolt to the factory standard base will bolt to our lowered base. We can not recommend installation of any brand of swivel adapter that dos not meet FMVSS 207 & 210. Our Scopema and Sportscraft brand swivels for the ProMaster are tested to meet these standards.

Q: Administrator's answer below seems to contradict your statement 'lower base can't be used without swivel". I want to lower stock drivers seat which does not have swivel. ( I am willing to modify side trim.) "Q: I very tall and need to lower the seat height, can these be used without swivel and just mount stock seat?

Asked by: Richard - 2/27/2023
A: We did not safety test the lower base without swivel installed, so we can not recommend it. This base is a lower version of the stock base, Installing it without a swivel will put your seat at a height not approved by the manufacture.
