RHS Vehicle Error 13

[]TPG[ Spectre 4]

I get a vehicle error 13 from trying to purchase RHS vehicles. from the research ive done, it seems that this error pertains to the vehicle not having enough space to spawn. this doesn't make any sense to me which ill explain, but i just wanted to point out that ive tried Tinboye replacement script for spawning vehicles from traders and i have attempted the solutions provide in another thread. 

Now the reason it doesn't make sense as to why the vehicles don't enough space to spawn is because one of the vehicles spitting out the error is a tiny dune buggy and the others are trucks and rg33's the smaller then the hemmet trucks i have working from the same mod pack. the largest vehicle i have can spawn at any of my traders no problem. so im just not sure what the deal is. please let me know if anyone can come up with a trouble shooting method for this or requires specific information to assist
