Hello, does anyone here have any recommendations for someone who can do a conversion (especially roof) that is safe, without breaking the bank? Also, I'm looking for any/all opinions on various converters and/or conversions. I'm thinking of doing a roof and rear conversion, because I was told by one converter that the rock n roll beds may not be as safe in an accident,, as they have not been crash tested in the actual vehicles the way the factory-fitted ones are. Any evidence to the contrary on that would also be welcome. Thank you!!
