h67st Posted December 19 Share Posted December 19 Here's a big hole R model but as you can see they did extensive bodywork to the cab. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74882-tito/#findComment-564283 Share on other sites More sharing options...
mowerman Posted December 19 Share Posted December 19 Hell , I must’ve missed this one truck looks gorgeous… walk in sleeper is the way to go, but yes, cutting up the body as a lot of work Quote Link to comment https://www.bigmacktrucks.com/topic/74882-tito/#findComment-564290 Share on other sites More sharing options...

That's a huge hole there, bigger than I expected to see I guess it is very hard to undo this in years to come if you change your mind But it would give you a lot more room in the bunk and possibly allow the seats to slide even further back Paul 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74882-tito/#findComment-564291 Share on other sites More sharing options...
Joseph Cummings Posted December 19 Share Posted December 19 When you open them up that big there are a lot of structural considerations. Probably be fine if you are building a trailer queen show truck, But if you put it to work you better have added some structural reinforcements or else that cab is going to crack starting with the upper rear corners of the door frame and getting worse. Have you ever seen an R Model that has been run with the bar between the steering axle's spring hangers that everyone thinks is just to hold up battery cables and the fuel crossover, missing or loose? It'll break the cab up just like that. And believe me, that is a hard fix 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74882-tito/#findComment-564294 Share on other sites More sharing options...
