Seems to me base on what you telling us you have everything under control and I am assuming you are not going sell your truck in future and down time is not a issue which is great
But – I being buying selling cars for last 30+ these are my toughs to other member’s:
• Stay away from body and Frame conversion.
• Engine modification you can do all you want.
• You like any new body style, sell your truck, and get the body style you want.

• The new conversation would no increase the resell value of your Truck., although may make it look good, but may effect your drive train and safety
• In case you need to sell your truck, limit’s # of Buyers
• In Texas you have to disclose any and all Frame work,,,,
• But if you are going do it, get it down with shop they have done and doing these type work and this is not their first experience and able to issue written warranty on their work.
